Description
GRAFTING OF MONOMERS ETHINICALLY INSATURED IN POLYMERS The present invention relates to a process for the preparation of grafted polymers, wherein in a first step A) a stable nitroxyl radical is grafted onto a polymer, this step comprises heating a polymer and a compound that contains a NO-ether above the melting point of the polymer, mixing and reacting the components at said temperature; and in a second step B) the grafted polymer of step A) is heated in the presence of an ethylenically unsaturated monomer or oligomer, at a temperature at which cleavage of the nitroxyl-polymer linkage occurs. Additional objects of the present invention are graft polymer prepared by the process, the intermediate polymeric radical initiator, the use of the polymeric radical initiator and the use of NO-ethers to insert polymers. Increased activities have been directed towards chemical modifications of existing polymers in order to obtain new functional and / or engineering materials. Chemical modifications of existing polymers are important for at least two reasons: 1. It can be an economical and quick way to get new polymers without having to look for new monomers; 2. It can be the
H | ^ -t? only way to synthesize polymers with the new intended characteristics. An important chemical modification is the grafting of free radicals of reactive monomers, which involves the reaction of a polymer with a monomer or mixture of monomers containing vinyl groups, capable of forming grafts on the polymer backbone. If the grafts are long, the modified polymer becomes a real graft copolymer, of which the properties will be very different from those of the original polymer substrate. When the grafts are short with less than, say, five portions, most of the physical and mechanical properties of the modified polymer substrate will be retained. The advantages of free radical grafting are further achieved with the use of batch mixers or screw or screw extruders, such as chemical reactors, which allow the free radical grafting reaction to occur without solvents. This is for example described by G. H. Hu et al., In "Reactive Modifiers for Polymers", first edition, Blackie Academic & Professional a Chapman print & Hall, London 1997, chapter 1, pages 1-97.
------------------------ t ^ These free radical grafting reactions are usually performed in the presence of a source of free radicals such as a peroxide or a reactive monomer, such as, for example, acrylic acid. However, the use of free radical sources such as peroxides can cause undesired properties and leads to problems during processing (gel formation, entanglement, molecular weight reduction) or during use. Typically, long-term stability is reduced and / or the polymer can no longer be used in outdoor applications or applications at elevated temperatures. The patent of the U.S.A. 4,581,429 issued to Solomon et al., On April 8, 1986, describes a free radical polymerization process that controls the growth of polymer chains to produce oligomeric or short chain homopolymers and copolymers, including block and graft copolymers. The process employs an initiator having the formula (in part) R'R1 'N-O-X, wherein X is a species of free radicals capable of polymerizing unsaturated monomers. Surprisingly, it has now been found that with specific compounds R'R,, N-0-X, it is possible to produce a polymeric radical initiator when grafting
_. A * l ^ a! S, the group R'R "N-O in the polymer and use this macroinitiator for additional grafting reactions of olefinically unsaturated monomers. The polymerization processes and the resin products of the present invention are useful in many applications, including a variety of specialty applications, such as the preparation of graft block copolymers which are useful as compatibilizing agents for polymer blends or dispersing agents for coating systems. An object of the present invention is a process for the preparation of a graft polymer wherein in a first step: A) a stable nitroxyl radical is grafted onto a polymer, this step comprises heating a polymer and a nitroxyl ether containing a group (= N0-X), where
X is chosen such that the cleavage of the O-X bond occurs and a radical X "is formed at about the melting temperature of the polymer; and in a second step B) the grafted polymer of step A) is heated in the presence of an ethylenically unsaturated monomer or oligomer at a temperature at which cleavage of the nitroxyl-polymer link occurs and the polymerization of the monomer or oligomer is initiated ethylenically unsaturated in the polymer radical; maintain the temperature for further polymerization and then cool the mixture to a temperature below 60 ° C. The reaction mixture after step A) can also be cooled to a temperature below 60 ° C, before further reaction of step B) is carried out. Optionally, a source is also present
free radicals. The reaction mixture after step A) can also be cooled to a temperature lower than 60 ° C before further reaction of step B) is carried out.

The grafted polymers are useful in many applications such as compatibilizers in mixtures of polymers or alloys, adhesion promoters between the two different substrates, surface modifying agents, nucleating agents, coupling agents between the filler and polymer matrix or dispersing agents. . The process is particularly useful for the preparation of block copolymers and grafted. The grafted block copolymers are for example block copolymers grafted from polystyrene 15 and polyacrylate (for example poly (styrene-co-acrylate) or poly (styrene-co-acrylate-co-styrene). They are useful as adhesives or as compatibilizers for polymer blends or as polymer curing agents Diblock copolymers poly (methyl methacrylate-co-acrylate) or triblock copolymers poly (methacrylate-co-acrylate-methacrylate), are useful as dispersing agents for coating system , as coating additives (for example rheological agents, compatibilizers, reactive diluents) or as resin components in

Because the present graft polymerization is an "active" polymerization, it can be started and stopped practically at will. In addition, the polymer product retains the functional alkoxyamine group allowing a continuation of the polymerization in a living material. Thus, in one embodiment of this invention, once the first monomer is consumed in the initial polymerization step, then a second monomer can be added to form a second block in the growing graft polymer chain in a second step of polymerization. It is therefore possible to carry out additional graft polymerizations with the same or different one or more monomers to prepare multi-block graft copolymers. In addition, since this is a radical polymerization, graft blocks can be prepared in essentially any order.

'^ ^^^^^ &? ^^ Loé SUMMARY OF THE INVENTION The present invention relates to a process for the preparation of a grafted polymer wherein in a first step A) a stable nitroxyl radical is grafted onto a polymer, this step comprises heating a polymer and a nitroxyl ether containing a group (= NO-X), wherein X is chosen such that the cleavage of the bond 0-X occurs and a radical X- is formed at about melting temperature of the polymer; and in a second step B) the grafted polymer of step A) is heated in the presence of a monomer or ethylenically unsaturated oligomer, a temperature at which cleavage of the nitroxyl-polymer occurs, and polymerizing the monomer or oligomer ethylenically unsaturated initiates in the polymer radical; maintain the temperature for further polymerization and then cool the mixture to a temperature below 60 ° C. Additional targets are grafted thermoplastic polymers that are prepared by the process, the intermediate polymeric radical initiator, the use of the polymeric radical initiator and the use of NO-ethers to graft thermoplastic polymers. ^ S? ^? ^ i? ^^ s mm ^? áai • ^^ 8 ^ te ^^^ te ^ a ^^
