polymerization catalysts. SUBSTANCE: invention relates to preparing cocatalyst for polymerization of butadiene carried out in presence of cobalt-containing catalysts and can be applied in production of cis-polybutadiene. Method consists in treatment at 50-70 C and stirring of triethylaluminum or triisobutylaluminum with carbon tetrachloride in toluene, molar ratio of the latter to trialkylaluminum being (0.30-0.40):1. EFFECT: decreased expenses on raw material, eliminated stages of replacement of solvent for trialkylaluminum and distilling off volatiles and solvent from reaction mixture, and reduced consumption of carbon tetrachloride. 4 ex |
