ABSTRACT:
A 1,3-cyclodiene is polymerized with a vinylaromatic hydrocarbon in the presence of a paraffin or cycloparaffin hydrocarbon diluent and an organolithium initiator. Further, polymerization of a 1,3-cyclodiene with a vinylaromatic hydrocarbon employing an organolithium initiator having a functionally greater than 1 produces a new and useful copolymer. Hydrogenated copolymers are provided.
