PROCESS FOR PRODUCING POLYBUTADIENE
A high cis-1,4-polybutadiene is produced, with a reduced gel formation, by preparing a catalyst from (A) a cobalt compound, (B) a trialkyl (C1-10) aluminum compound, (C) a halide compound selected from those of the formulae (1) and (2): AlR2m X3-m(1), R3-X(2), wherein R2 = C1-10 hydrocarbon, X = hal...

Summary: | A high cis-1,4-polybutadiene is produced, with a reduced gel formation, by preparing a catalyst from (A) a cobalt compound, (B) a trialkyl (C1-10) aluminum compound, (C) a halide compound selected from those of the formulae (1) and (2): AlR2m X3-m(1), R3-X(2), wherein R2 = C1-10 hydrocarbon, X = halogen, m = 0 to 2, R3 = C1-40 hydrocarbon, and (D) water in an amount of 0.77 to 1.45 moles per mole of total A1 in the component (B) and (C); and polymerizing 1,3-butadiene in the presence of the resultant catalyst in a polymerization medium including an alkane, cycloalkane and/or olefin hydrocarbon. |
