| SU1655601A SU429589A3 (en) | 1970-05-14 | 1971-05-13 | METHOD FOR OBTAINING BUTADIENE-PROPYLENE COPPER POLYMERS 1 The invention relates to the production of elastic statistical copolymers of butadiene and propylene. C in the presence of a complex organometallic catalyst consisting of titanium tetrahalides and trialkylaluminum. The copolymers obtained are of commercial interest, since physical and mechanical properties, such as strength, tear resistance, heat resistance, and anti-friction properties, can be significantly improved. However, the amount of propylene in the resulting copolymer is small, it enters the copolymer in the form of blocks, so the copolymer does not possess the desired properties and cannot be used as an elastomer. In order to obtain statistical copolymers with improved elasticity, it is proposed to use a catalyst consisting of titanium compounds or vanadium and the product of the reaction of phosgene with organoaluminum compounds of the general formula 2AlRiR2R3, where Ri, R2.n Rs - GI - Cis are hydrocarbon radicals, 5 with a molar ratio of titanium or vanadium to organoaluminum to whom the compound 1: 1-1: 10 and the organoaluminum compound to phosgene 10: 1-1: 1. With the help of the proposed catalyst for the polymerization of 1,3-butadiene with propylene, the amount of propylene in the copolymer can be increased and the copolymer can be used as elastomer. Thus, the following advantages are achieved: 15 the resulting statistical copolymer is a high molecular weight rubber-like elastomer; propylene units are well dispersed in the copolymer; 20 a small amount of gel or solvent insoluble is formed; the polymerization proceeds quickly and evenly from beginning to end. 25 elastomer by any desired method on an industrial scale. The first component of the catalyst is titanium or vanadium compounds, for example, tetrachloride en 30 chetyreh'bromisty titanium trichloride five- |
