FIELD: polymerization catalysts.
SUBSTANCE: catalyst is prepared by mixing hydrocarbon solutions of titanium tetrachloride, triisobutylaluminum-diphenyl oxide complex, and 1,3-pentadiene at Al/Ti molar ratio from 0.9:1 to 1.2:1 and at temperature form -70 to +20°C, after which mixture of paraffin, aromatic, and naphthene hydrocarbons is added, in particular industrial or transformer oil in amount 0.05 to 2% on the weight of catalyst suspension.
EFFECT: increased catalytic activity and reduced dosage of catalyst in polymerization process, which allows production of rubber with reduced titanium compound level without increasing intensity of washing away titanium compounds.
