摘要： Polymerizations of conjugated diolefins are interesting topics in rubber and thermoplastic elastomer industries. Especially the copolymerization of butadiene(Bd) and isoprene (Ip) takes an important place in tire. Many investigations on rare earth catalysts system for the copolymerization have been reported, but rarely reported on that of using alkyllithium as initiator. In the research, it is reported a study on the copolymerization of Bd and Ip at 50 ℃ in the presence of diglycoldimethyl ether(2 G)and n-BuLi as initiator, cyclohexane as solvent.
