ABSTRACT:
A copolymer is produced by polymerization of a mixture comprising a 1,3-cyclodiene and an acyclic conjugated diene wherein a substantial percentage by weight of the acyclic conjugated diene units of the copolymer is in the trans and vinyl configurations. A method for producing the copolymer is provided employing an organolithium initiator. A hydrogenated copolymer and method of its production is also provided.
