Abstract

PURPOSE: To prepare a vinyl-containing polybutadiene having excellent cold-flow characteristic, and easily controllable Mooney viscosity, by polymerizing butadiene in the presence of a polar compound, a branching agent. a lithium catalyst, and a specific amount of an allene based on the catalyst.
CONSTITUTION: The objective polymer containing ≥30mol% of vinyl group, based on the monomer units, is prepared by polymerizing (A) 1,3-butadiene, in the presence of (B) one or more polar compounds such as ethers, amines, phosphines, sulfides, etc., (C) a branching agent such as a polyvinyl aromatic compound, (D) a lithium-based catalyst such as n-butyl lithium, and (E) 1W1/35mol, based on 1mol of the (D) component, of an allene derivative of formula (R is H or 1W5C hydrocarbon), pref. at 25W90°C.
