METHOD OF PREPARING COMPLEX COBALT-CONTAINING CATALYST

摘要

FIELD: polymerization catalysts. SUBSTANCE: invention relates to preparing butadiene polymerization catalyst that can find use in preparing catalysts for polymerization of dienes and olefins. Toluene solutions of cobalt compound and alkylaluminum chloride are added to toluene containing 0.010-0.035 wt % water and part of monomer thermostatically controlled at temperature from -30 to -25 C over the period of time from 10 min to 24 hr. Resulting solution is suitable for catalyzing 1,4-cys-polymerization of butadiene in aliphatic hydrocarbon (hexane, gasoline, etc.). EFFECT: enabled polymerization control with no need of additional reagents and allowed utilization of aliphatic hydrocarbon medium to carry out the process. 1 tbl, 3 ex
