Polyarylene ethers containing tetraphenylethylene units Abstract Polyarylene ethers which contain, based on the total amount of structural elements present in the polymer, 2-100 mol% of one or more recurring structural elements of the formula Ia, Ib or Ic (Ia), (Ib), (Ic) and 0-98 mol% of a recurring structural element of the formula II

Polvarvlene ethers containin~ tetraphenvlethYlene unlts The invention relates to novel, specified polyarylene ethers containing tetraphenylethylene units, to a process for their preparation, and to their use, and to specific diphenol isomer mixtures as the monomer components for the synthesis of polyarylene ethers and to a process for the preparation of these isomer mixtures.
Polyarylene ethers are industrial materials having very good mechanical and therrnal properties and high resistance to conventional organic solvents. For some applications, however, this solvent resistance is undesired. In particular, the modification of thermoset matrix resins requires the use of the most concentrated polymer solutions possible in conventional organic solvents. The object of the present invention was therefore to provide polyarylene ethers having very good solubility in a wide range of organic solvents.
This object is achieved by using bis(4-hydroxyphenyl)diphenylethylene as a monomer component.
The invention accordingly relates to a polyarylene ethers which contain, based on the total amount of structural elements present in the polymer, 2-100 mol% of one or more recurring structural elements of the forrnula Ia, Ib or Ic ¦ O O-Ar1~ _ _ \~ (Ia), )=~ (Ib), L ~ ~ O-Ar~ t 20~7~1 _ o O-Ar1- _ and 0-98 mol% of a recurring structural element of the formula II

Polyarylene ethers containing a tetraphenylethylene structure are hitherto unknown in the literature.
The only known po!ymers which contain a tetraphenylethylene unit are polyamides and polyimides (Y. Oishi et al., Pol. Mat. Sci. Eng. 1989, 60, 757). The polymers described therein are synthesised starting from 4,4'-diaminotetraphenylethylene; depending on the 4~ Z~0~
coreactant, they are soluble in aprotic, dipolar solvents, such as N-methylpyrrolidone, dimethyl sulfoxide, dimethylacetarnide or pyridine. However, solubility properties of this type are in no way excellent for polyamides or polyimides since other known polymers, for example the polyimides of US Patent 3 856 752 and European Patent Application 92 524, which are derived from diaminotrimethylphenylindane have significantly better solubilities. Further polyamides containing tetraphenylethylene units are described in J. of Polymer Science, Part A, 1991, Vol. 29, 55-61.
It ~vas therefore surprising that the polyarylene ethers according to the invention based on tetraphenylethylene units have particularly good solubilities in conventional organic solvents, such as chlorinated hydrocarbons, cyclic ketones or cyclic ethers.
Other known polyarylene ethers whose monomer component likewise contains four phenyl groups, for example the polyarylene ethers of German Patent Application 3 825 148 which are derived from 4,4'-dihydroxy-3,3'-diphenylbiphenyl do not have the excellent solubility properties of the present compounds.
The polyarylene ethers according to the invention can be prepared by polycondensing one or more diphenols of the forrnula Va, Vb or Vc HO OH HO

Il (Vc) ~3 7~
and, if desired, a diphenol of the fonnula VI
HO-Ar2-OH (VI) with a dihalogen derivative of the forrnula VII
Hal-Arl-Hal (VII) in the presence of an aLlcaline catalyst in a polar aprotic solvent, Arl and Ar2 being as de~ned above, and Hal being halogen, in particular fluorine or chlorine, and the relative amounts of the diphenol of the ~ormula Va IO Vc and of the diphenol of the ~onnula VI
being selec~ed in such a manner that the resultant copolymer contains the amounts defined in claim 1 of the structural elements of the formulae I and II.
The diphenols of the formula V or VI may also be replaced by the corresponding aLkali or alkaline earth metal phenoxides, for example potassium phenoxide or calcium phenoxide.
The polycondensation is usually carried out in approximately equimolar ratios of the diphenols of the forrnulae V and, if used, VIi based on the dihalogen derivative of the formula VII. Approximately equimolar arnounts is taken to mean a molar ratio of 0.8:1.0 to 1.0:0.8; a molar ratio of 0.95:1.00 to 1.00:0.95 is preferred.
The copolymers containing both structural elements of the ~orrnula I and structural elements of the fonnula II can be prepared either in a random manner or in a segmented manner (block copolymers). In the random-type synthesis, a mixture of the phenols V and VI is, for example, condensed with one or more dihalogen derivatives of the fonnula VII.
To prepare a block copolymer, products of the reaction of a diphenol of the forrnula V and a dihalogen derivative of the fonnula VII containing hydroxyl or phenoxide end groups and products of the reaction of a diphenol of the formula VI and a dihalogen derivative of the formula VII containing halogen end groups, or vice versa, are synthesised. This is achieved, as is known, by using an appropriate excess of the diphenol or of the dihalogen derivative in the preparation of the reaction product. An appropriate excess of one of the starting materials is, for example, an excess of from about 1 to 50 mol%. The extent of the excess in each case deterrnines the block length.

The aL~aline catalyst used in the process according to the invention is generally an alkali metal carbonate or aL~caline earth metal carbonate or a corresponding bicarbonate, such as sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, calcium carbonate or calcium bicarbonate; however, it is also possible to employ other alkaline reagents, such as sodium hydroxide, potassium hydroxide or calcium hydroxide.
Examples of polar aprotic solvents which can be employed for the preparation of the polyarylene ether resins according to the invention are dimethyl sulfoxide, dimethylacetamide, diethylacetamide, tetramethylurea, N-methylcaprolactam, N-methylpyrrolidone and pre~erably diphenyl sulfone.
The reaction is expediently carried out at elevated temperature, preferably up to the reflux temperature of the solvent, for example up to about 350C.
It is frequently advisable concomitantly to use an entrainer, for example chlorobenzene, xylene or toluene, in order to facilitate azeotropic removal from the reaction mixture of the water formed during the reaction.
The compounds of the formula VII are known. Some are commercially available and some can be prepared in a known manner.
Examples of suitable compounds of the formula VII ale 4,4'-dichloro- or4,4'-difluorodiphenyl sulfoxide or-diphenyl sulfone, 4,4'-dichloro- or 4,4'-difluorobenzophenone, 4,4'-dichloroisophthalophenone and 4,4'-dichloroterephthalophenone, or 2,6-difluorobenzonitrile or 2,6-dichlorobenzonitrile.
Preferred compounds of the formula VII are 4,4'-difluorobenzophenone and, in particular, 4,4'-dichlorodiphenyl sulfone.
Compounds of the formula VI are likewise known and commercially available. Examples of suitable compounds of the formula VI are hydroquinone, 4,4'-dihydroxybiphenyl, 2-phenylhydroquinone, 2,6- and 2,7-dihydroxynaphthalene, bisphenol A, bisphenol F, 4,4'-dihydroxybenzophenone, 4,4'-dihydroxydiphenyl ether, 4,4'-dihydroxydiphenylsulfide, 4,4'-dihydroxydiphenyl sulfoxide, 4,4'-dihydroxydiphenyl sulfone and 2,2-bis(4'-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane, and the corresponding 204'73Bl C~-C4alkyl-substitu~ed derivatives, for example 3,3',5,5'-tetrarnethyl-4,4'-dihydroxydiphenyl sulfone.
Further suitable compounds are: 2,2'-dihydroxybiphenyl, 9,9-bis(4'-hydroxyphenyl)fluorene and 6,6'-dihydroxy-3,3,3',3'-tetramethyl- 1, l '-spirobiindane.
Preferred compounds of the formula VI are 4,4'-dihydr~xybiphenyl, 4,4'-dihydroxybenzophenone, hydroquinone and bisphenol A.
A particularly preferred compound of the formula VI is 4,4'-dihydroxydiphenyl sulfone.
The diphenols of the formulae Va, Vb and Vc are known or can be prepared in a known manner. A suitable synthetic route for the preparation of 1,2-bis(4'-hydroxyphenyl)-1,2-diphenylethylene is descAbed by R.N. Iyer and K.V.B. Rao in Ind. J. Chem., 16B, 601 (1978). The first step is conversion of 4-methoxybenzophenone into 4-methoxyphenylphenyldichloromethane using PCI5, followed by dimeAsation of the resultant dichloromethane derivative to give the tetrasubstituted ethylene derivative by heating in a solvent in the presence of elemental copper, and subsequently cleavage of the methyl ether by heating with potassium hydroxide in diethylene glycol. An analogous synthesis of tetraphenylethylene derivatives starting from unsubstituted benzophenone is described in Org. Synth. Coll. Vol. II, 573 (1943) and Coll. Vol. IV, 914 (1963~.
It has been found that particularly highly soluble polyarylene ethers are obtained if the diphenol component used in their preparation is a dihydroxytetraphenyl isomer mixture containing the diphenols of the formulae Va, Vb and Vc. This isomer mixture is novel and is likewise a subject-matter of the present invention. Particular preference is given to an isomer mixture containing the diphenols Va, Vb and Vc in a molar ratio of about 2:2:1.
The isomer mixture according to the invention is obtainable, for example, by cleaving the above-described tetraphenylethylenedimethyl ether in a highly acidic medium, forexample using HBr in glacial acetic acid, whereas the corresponding alkaline cleavage described in Ind. J. Chem. 1978, 16 B, 601 gives a mixture containing only two isomers.
This preparation process for the isomer mixture is likewise a subject-matter of the present invention.
The polyarylene ethers according to the invention preferably contain 15-100 mol%, in particular lO-100 mol%, of a recurring structural element of the formula I and 0-95 mol%, in particular Q-90 mol%, of a recurring structural element of the formula r[. Arl and Ar2 in the formulae I and Il are particularly preferably a radical of the forrnula 3 SO2~-, or Arl is a radical of the forrnula SO2~ and Ar2 is a radical of the formula ~3' Particularly preferred polyarylene ethers contain 25-100 mol% of a recurring structural element of the formula I and 0-75 mol% of a recurring structural element of the formula II.
In the formulae IVa and IVb, X is preferably -SO2-. The Arl group is preferably the radical ~3 SO2~ .
Z in the formulae IIId and IIIe is preferably -C(CH3)2-, -CO-, -SO2-, -S- or -O-.
The phenylene groups in the forrnulae IIIa to IIIe and IVa and IVb are preferably 1,3- and in particular 1,4-phenylene groups. Ihe aLIcyl or aLlcoxy substituents of the groups Arl and Ar2 may be straight-chain or branched. Examples of suitable substituents are ethyl, n-propyl, isopropyl, n-butyl and in particular me~yl, and the corresponding alkoxy groups. Preferred groups Arl and Ar2 are unsubstituted.
The Ar2 group of the compounds according to the invention is preferably a radical of the forrnula ,~
3 CH~;--or in particular {3 So2~3 .
The polyarylene ethers according to the invention preferably have a reduced viscosity of from 0.1 to 2.0 dVg, in particular from 0.3 to 1.5 dVg, measured at 25C on a 1% solution in N-methylpyrrolidone (1 g of polymer dissolved in lOQ ml of NMP).
The polyarylene ethers according to the invention can be employed in a manner conventional for thermoplastics and can be converted, for exarnple, into mouldings or films, or can be employed as matrix resins, adhesives or coating compositions. Before the polyarylene ethers, in the form, for example, of a moulding powder, melt or solution, are processed, conventional additives, for example fillers, pigments, stabilisers or reinforcing agents, such as carbon fibres, boron fibres or glass fibres, can be added. The polyarylene ethers according to the invention can also be processed together with other therrnoplastics.
The polyarylene ethers according to the invention are preferably suitable as ma~ix resins for the production of fibre-composite systems, suitable reinforcing fibres being the conventional fibres used to reinforce industrial materials. These may be organic or inorganic fibres, natural fibres or synthetic fibres, such as aramid fibres, and in the forrn of fibre bundles, oriented or nonoriented fibres or continuous fibres. Examples of reinforcing fibres used are glass fibres, boron fibres, carbon fibres and metal fibres.
A further preferred possible use of the polyarylene ethers according to the invention is for Z~3~.
- ]o -the modificadon of other plastics. These plastics may in principle be thermoplasdcs or thermosets. The moclification of thermocurable resins, in particular epoxy resins or bismaleimides, has achieved particulau importance. Polymer systems customised topardcular requirements of this type are described, for example, in US Patent 3,530,087.
Systems of this type have achieved particular importance as matrix resins for the producdon of composite elements. From about 5-1~0 parts by weight, preferably 10-50 parts by weight, of polyarylene ether are usually employed per 100 parts by weight of the plastics to be modified.
The present invention thus also provides mouldings, ~llms, coadngs or adhesive bonds containing a polyarylene ether according to the invendon, and fibre composites containing reinforcing fibres and, as matrix resin, a polyarylene ether according to the invendon.
Specific mendon should be made of both the very good solubility of the polymers according to the invention in a wide range of organic solvents (for example in chlorinated hydrocarbons, cyclic ketones and cyclic ethers) and the very good stability of these solutions. The polymers can thus be processed from solution, for example to give films, or introduced into other systems, for example matrix resins. Solutions containing 1-75 % by weight, preferably 5-40 % by weight, of the polyarylene ethers according to the inventdon in an organic solvent are thus a further subject-matter of the invention. Examples of preferred organic solvents are N-methylpyrrolidone, ~-butyrolactone, dimethylacetamide, dimethyl sulfoxide, cyclohexanone, cyclopentanone, 1,3-dioxolane and methylene chloride. Preferred soludons contain a polyarylene ether containing 5-100 mol%, preferably 10-100 mol%, of a recurring structural element of the forrnula I and 0-95 mol%, preferably 0-90 mol%, of a recurring structural element of the formula II.

Towards the end of the distillation operation, a vacoum (2 mbar) is applied briefly. 15.38 g (0.0501 mol) of 4,4'-dichlorodiphenyl sulfone are then added to the reaction mixture, and the temperature is increased to 228C over the course of 15 minutes and kept there for 1 hour. The temperature is then increased to 250C (1 hour~ and subsequently to 280C. This temperature is maintained for 4 hours.
0.040 g (0.0014 mol) of 4,4'-dichlorodiphenyl sulfone are then added at this temperature.
This operation is filtered after 30 minutes and again after 15 minutes. After a further 30 minutes, the viscous reaction mixture is cooled briefly and removed from the reaction flask.
The solidified reaction mixture is powdered, then treated with acetic acid and extracted with water. The polymer is subsequently dissolved in methylene chloride, a small amount of insoluble material is filtered off, and the dissolved product is then precipitated using isopropanol. I he polymer purified in this way is then dried at 240C in a vacuum drying oven. A polyarylene ether sulfone prepared in this way has a reduced viscosity [1 % by weight of polymer in N-methylpyrrolidone (NMP) at 25C] of 0.29 dlJg.

Polvarvlene ethers containin~ tetraphenvlethYlene unlts The invention relates to novel, specified polyarylene ethers containing tetraphenylethylene units, to a process for their preparation, and to their use, and to specific diphenol isomer mixtures as the monomer components for the synthesis of polyarylene ethers and to a process for the preparation of these isomer mixtures.
Polyarylene ethers are industrial materials having very good mechanical and therrnal properties and high resistance to conventional organic solvents. For some applications, however, this solvent resistance is undesired. In particular, the modification of thermoset matrix resins requires the use of the most concentrated polymer solutions possible in conventional organic solvents. The object of the present invention was therefore to provide polyarylene ethers having very good solubility in a wide range of organic solvents.
This object is achieved by using bis(4-hydroxyphenyl)diphenylethylene as a monomer component.
The invention accordingly relates to a polyarylene ethers which contain, based on the total amount of structural elements present in the polymer, 2-100 mol% of one or more recurring structural elements of the forrnula Ia, Ib or Ic ¦ O O-Ar1~ _ _ \~ (Ia), )=~ (Ib), L ~ ~ O-Ar~ t 20~7~1 _ o O-Ar1- _ and 0-98 mol% of a recurring structural element of the formula II

Polyarylene ethers containing a tetraphenylethylene structure are hitherto unknown in the literature.
The only known po!ymers which contain a tetraphenylethylene unit are polyamides and polyimides (Y. Oishi et al., Pol. Mat. Sci. Eng. 1989, 60, 757). The polymers described therein are synthesised starting from 4,4'-diaminotetraphenylethylene; depending on the 4~ Z~0~
coreactant, they are soluble in aprotic, dipolar solvents, such as N-methylpyrrolidone, dimethyl sulfoxide, dimethylacetarnide or pyridine. However, solubility properties of this type are in no way excellent for polyamides or polyimides since other known polymers, for example the polyimides of US Patent 3 856 752 and European Patent Application 92 524, which are derived from diaminotrimethylphenylindane have significantly better solubilities. Further polyamides containing tetraphenylethylene units are described in J. of Polymer Science, Part A, 1991, Vol. 29, 55-61.
It ~vas therefore surprising that the polyarylene ethers according to the invention based on tetraphenylethylene units have particularly good solubilities in conventional organic solvents, such as chlorinated hydrocarbons, cyclic ketones or cyclic ethers.
Other known polyarylene ethers whose monomer component likewise contains four phenyl groups, for example the polyarylene ethers of German Patent Application 3 825 148 which are derived from 4,4'-dihydroxy-3,3'-diphenylbiphenyl do not have the excellent solubility properties of the present compounds.
The polyarylene ethers according to the invention can be prepared by polycondensing one or more diphenols of the forrnula Va, Vb or Vc HO OH HO

Il (Vc) ~3 7~
and, if desired, a diphenol of the fonnula VI

Hal-Arl-Hal (VII) in the presence of an aLlcaline catalyst in a polar aprotic solvent, Arl and Ar2 being as de~ned above, and Hal being halogen, in particular fluorine or chlorine, and the relative amounts of the diphenol of the ~ormula Va IO Vc and of the diphenol of the ~onnula VI
being selec~ed in such a manner that the resultant copolymer contains the amounts defined in claim 1 of the structural elements of the formulae I and II.
The diphenols of the formula V or VI may also be replaced by the corresponding aLkali or alkaline earth metal phenoxides, for example potassium phenoxide or calcium phenoxide.
The polycondensation is usually carried out in approximately equimolar ratios of the diphenols of the forrnulae V and, if used, VIi based on the dihalogen derivative of the formula VII. Approximately equimolar arnounts is taken to mean a molar ratio of 0.8:1.0 to 1.0:0.8; a molar ratio of 0.95:1.00 to 1.00:0.95 is preferred.
The copolymers containing both structural elements of the ~orrnula I and structural elements of the fonnula II can be prepared either in a random manner or in a segmented manner (block copolymers). In the random-type synthesis, a mixture of the phenols V and VI is, for example, condensed with one or more dihalogen derivatives of the fonnula VII.
To prepare a block copolymer, products of the reaction of a diphenol of the forrnula V and a dihalogen derivative of the fonnula VII containing hydroxyl or phenoxide end groups and products of the reaction of a diphenol of the formula VI and a dihalogen derivative of the formula VII containing halogen end groups, or vice versa, are synthesised. This is achieved, as is known, by using an appropriate excess of the diphenol or of the dihalogen derivative in the preparation of the reaction product. An appropriate excess of one of the starting materials is, for example, an excess of from about 1 to 50 mol%. The extent of the excess in each case deterrnines the block length.

The aL~aline catalyst used in the process according to the invention is generally an alkali metal carbonate or aL~caline earth metal carbonate or a corresponding bicarbonate, such as sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, calcium carbonate or calcium bicarbonate; however, it is also possible to employ other alkaline reagents, such as sodium hydroxide, potassium hydroxide or calcium hydroxide.
Examples of polar aprotic solvents which can be employed for the preparation of the polyarylene ether resins according to the invention are dimethyl sulfoxide, dimethylacetamide, diethylacetamide, tetramethylurea, N-methylcaprolactam, N-methylpyrrolidone and pre~erably diphenyl sulfone.
The reaction is expediently carried out at elevated temperature, preferably up to the reflux temperature of the solvent, for example up to about 350C.
It is frequently advisable concomitantly to use an entrainer, for example chlorobenzene, xylene or toluene, in order to facilitate azeotropic removal from the reaction mixture of the water formed during the reaction.
The compounds of the formula VII are known. Some are commercially available and some can be prepared in a known manner.
Examples of suitable compounds of the formula VII ale 4,4'-dichloro- or4,4'-difluorodiphenyl sulfoxide or-diphenyl sulfone, 4,4'-dichloro- or 4,4'-difluorobenzophenone, 4,4'-dichloroisophthalophenone and 4,4'-dichloroterephthalophenone, or 2,6-difluorobenzonitrile or 2,6-dichlorobenzonitrile.
Preferred compounds of the formula VII are 4,4'-difluorobenzophenone and, in particular, 4,4'-dichlorodiphenyl sulfone.
Compounds of the formula VI are likewise known and commercially available. Examples of suitable compounds of the formula VI are hydroquinone, 4,4'-dihydroxybiphenyl, 2-phenylhydroquinone, 2,6- and 2,7-dihydroxynaphthalene, bisphenol A, bisphenol F, 4,4'-dihydroxybenzophenone, 4,4'-dihydroxydiphenyl ether, 4,4'-dihydroxydiphenylsulfide, 4,4'-dihydroxydiphenyl sulfoxide, 4,4'-dihydroxydiphenyl sulfone and 2,2-bis(4'-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane, and the corresponding 204'73Bl C~-C4alkyl-substitu~ed derivatives, for example 3,3',5,5'-tetrarnethyl-4,4'-dihydroxydiphenyl sulfone.
Further suitable compounds are: 2,2'-dihydroxybiphenyl, 9,9-bis(4'-hydroxyphenyl)fluorene and 6,6'-dihydroxy-3,3,3',3'-tetramethyl- 1, l '-spirobiindane.
Preferred compounds of the formula VI are 4,4'-dihydr~xybiphenyl, 4,4'-dihydroxybenzophenone, hydroquinone and bisphenol A.
A particularly preferred compound of the formula VI is 4,4'-dihydroxydiphenyl sulfone.
The diphenols of the formulae Va, Vb and Vc are known or can be prepared in a known manner. A suitable synthetic route for the preparation of 1,2-bis(4'-hydroxyphenyl)-1,2-diphenylethylene is descAbed by R.N. Iyer and K.V.B. Rao in Ind. J. Chem., 16B, 601 (1978). The first step is conversion of 4-methoxybenzophenone into 4-methoxyphenylphenyldichloromethane using PCI5, followed by dimeAsation of the resultant dichloromethane derivative to give the tetrasubstituted ethylene derivative by heating in a solvent in the presence of elemental copper, and subsequently cleavage of the methyl ether by heating with potassium hydroxide in diethylene glycol. An analogous synthesis of tetraphenylethylene derivatives starting from unsubstituted benzophenone is described in Org. Synth. Coll. Vol. II, 573 (1943) and Coll. Vol. IV, 914 (1963~.
It has been found that particularly highly soluble polyarylene ethers are obtained if the diphenol component used in their preparation is a dihydroxytetraphenyl isomer mixture containing the diphenols of the formulae Va, Vb and Vc. This isomer mixture is novel and is likewise a subject-matter of the present invention. Particular preference is given to an isomer mixture containing the diphenols Va, Vb and Vc in a molar ratio of about 2:2:1.
The isomer mixture according to the invention is obtainable, for example, by cleaving the above-described tetraphenylethylenedimethyl ether in a highly acidic medium, forexample using HBr in glacial acetic acid, whereas the corresponding alkaline cleavage described in Ind. J. Chem. 1978, 16 B, 601 gives a mixture containing only two isomers.
This preparation process for the isomer mixture is likewise a subject-matter of the present invention.
The polyarylene ethers according to the invention preferably contain 15-100 mol%, in particular lO-100 mol%, of a recurring structural element of the formula I and 0-95 mol%, in particular Q-90 mol%, of a recurring structural element of the formula r[. Arl and Ar2 in the formulae I and Il are particularly preferably a radical of the forrnula 3 SO2~-, or Arl is a radical of the forrnula SO2~ and Ar2 is a radical of the formula ~3' Particularly preferred polyarylene ethers contain 25-100 mol% of a recurring structural element of the formula I and 0-75 mol% of a recurring structural element of the formula II.
In the formulae IVa and IVb, X is preferably -SO2-. The Arl group is preferably the radical ~3 SO2~ .
Z in the formulae IIId and IIIe is preferably -C(CH3)2-, -CO-, -SO2-, -S- or -O-.
The phenylene groups in the forrnulae IIIa to IIIe and IVa and IVb are preferably 1,3- and in particular 1,4-phenylene groups. Ihe aLIcyl or aLlcoxy substituents of the groups Arl and Ar2 may be straight-chain or branched. Examples of suitable substituents are ethyl, n-propyl, isopropyl, n-butyl and in particular me~yl, and the corresponding alkoxy groups. Preferred groups Arl and Ar2 are unsubstituted.
The Ar2 group of the compounds according to the invention is preferably a radical of the forrnula ,~
3 CH~;--or in particular {3 So2~3 .
The polyarylene ethers according to the invention preferably have a reduced viscosity of from 0.1 to 2.0 dVg, in particular from 0.3 to 1.5 dVg, measured at 25C on a 1% solution in N-methylpyrrolidone (1 g of polymer dissolved in lOQ ml of NMP).
The polyarylene ethers according to the invention can be employed in a manner conventional for thermoplastics and can be converted, for exarnple, into mouldings or films, or can be employed as matrix resins, adhesives or coating compositions. Before the polyarylene ethers, in the form, for example, of a moulding powder, melt or solution, are processed, conventional additives, for example fillers, pigments, stabilisers or reinforcing agents, such as carbon fibres, boron fibres or glass fibres, can be added. The polyarylene ethers according to the invention can also be processed together with other therrnoplastics.
The polyarylene ethers according to the invention are preferably suitable as ma~ix resins for the production of fibre-composite systems, suitable reinforcing fibres being the conventional fibres used to reinforce industrial materials. These may be organic or inorganic fibres, natural fibres or synthetic fibres, such as aramid fibres, and in the forrn of fibre bundles, oriented or nonoriented fibres or continuous fibres. Examples of reinforcing fibres used are glass fibres, boron fibres, carbon fibres and metal fibres.
A further preferred possible use of the polyarylene ethers according to the invention is for Z~3~.

Systems of this type have achieved particular importance as matrix resins for the producdon of composite elements. From about 5-1~0 parts by weight, preferably 10-50 parts by weight, of polyarylene ether are usually employed per 100 parts by weight of the plastics to be modified.
The present invention thus also provides mouldings, ~llms, coadngs or adhesive bonds containing a polyarylene ether according to the invendon, and fibre composites containing reinforcing fibres and, as matrix resin, a polyarylene ether according to the invendon.
Specific mendon should be made of both the very good solubility of the polymers according to the invention in a wide range of organic solvents (for example in chlorinated hydrocarbons, cyclic ketones and cyclic ethers) and the very good stability of these solutions. The polymers can thus be processed from solution, for example to give films, or introduced into other systems, for example matrix resins. Solutions containing 1-75 % by weight, preferably 5-40 % by weight, of the polyarylene ethers according to the inventdon in an organic solvent are thus a further subject-matter of the invention. Examples of preferred organic solvents are N-methylpyrrolidone, ~-butyrolactone, dimethylacetamide, dimethyl sulfoxide, cyclohexanone, cyclopentanone, 1,3-dioxolane and methylene chloride. Preferred soludons contain a polyarylene ether containing 5-100 mol%, preferably 10-100 mol%, of a recurring structural element of the forrnula I and 0-95 mol%, preferably 0-90 mol%, of a recurring structural element of the formula II.
The examples below illustrate the invention.

Example 2: PolYether sulfone made from bis(4-hydroxYphenYl)diphenYlethvlene (isomer mixture) and 4~4'-dichlorodiphenYl sulfone A mixture of 18.34 g (0.0503 mol) of bis(4-hydroxyphenyl)diphenylethylene (isomer mixture), 59.31 g of diphenyl sulfone, 7.30 g (0.0528 mol) of potassium carbonate and 52 g of xylene is heated at a bath temperature of 200C under nitrogen in a round-bottomed flask fitted wi~h stirrer and protective-gas inlet, and a xylene/water mixture is removed by distillation. Towards the end of the distillation operation, a vacoum (2 mbar) is applied briefly. 15.38 g (0.0501 mol) of 4,4'-dichlorodiphenyl sulfone are then added to the reaction mixture, and the temperature is increased to 228C over the course of 15 minutes and kept there for 1 hour. The temperature is then increased to 250C (1 hour~ and subsequently to 280C. This temperature is maintained for 4 hours.
0.040 g (0.0014 mol) of 4,4'-dichlorodiphenyl sulfone are then added at this temperature.
This operation is filtered after 30 minutes and again after 15 minutes. After a further 30 minutes, the viscous reaction mixture is cooled briefly and removed from the reaction flask.
The solidified reaction mixture is powdered, then treated with acetic acid and extracted with water. The polymer is subsequently dissolved in methylene chloride, a small amount of insoluble material is filtered off, and the dissolved product is then precipitated using isopropanol. I he polymer purified in this way is then dried at 240C in a vacuum drying oven. A polyarylene ether sulfone prepared in this way has a reduced viscosity [1 % by weight of polymer in N-methylpyrrolidone (NMP) at 25C] of 0.29 dlJg. The glass transition temperature, determined by DSC, is 215C. The 13C NMR spectrum of thepolyether sulfone shows signals comparable to the monomer (Example lb~ in addition to the diphenyl sulfone unit. In particular, the unchanged presence of the C-C double bond can be seen. The particularly good solubility of this polymer can be seen from the table below.
