Abstract

Abstract A butadiene polymer consisting essentially of syndiotactic 1,2polybutadiene is produced by the successive steps of: (A) preparing a catalyst component solution by dissolving, in an inert organic solvent containing 1,3-butadiene, a cobalt compound, soluble in the organic solvent, such as (i) cobaltBeta -diketone complex, (ii) cobalt- Beta -keto-acid ester complex, (iii) cobalt salt of organic carboxylic acid and (iv) halogenated cobalt-ligand compound complex, and an organoaluminum commpound, (B) preparing a catalyst composition by mixing the catalyst component solution with an alcohol, ketone or aldehyde compound and carbon disulfide; (C) providing a polymerization mixture containing desired amounts of 1,3-butadiene, the catalyst composition and an inert organic solvent, and (D) polymerizing 1,3-butadiene at a temperature of -20* to 80*C.
