    摘要: A catalyst system suitable for use in the production of high cis polybutadiene is disclosed. The catalyst system includes a cobalt salt of the formulaCoAx?, where A is a monovalent or divalent anion and x is 1 or 2; an alkyl aluminum chloride compound of the structure R2AlCl, where R is an alkyl group containing 2-8 carbon atoms; a trialkyl aluminum compound of the formula R3Al, where R is an alkyl group containing 2-8 carbon atoms; and a catalytic amount of water.
