Halogenated polybutadiene series elastomers, method of producing the same and rubber compositions for tire containing this elastomer

摘要

A novel halogenated polybutadiene series elastomer is produced by reacting a polybutadiene series elastomer with a particular active halogen group-containing compound in the presence of a particular organic halogenating agent. The resulting halogenated polybutadiene series elastomer can be subjected to heat-resistant crosslinking with a particular polyvalent amine, and is suitable for the preparation of rubber compositions for tire requiring the heat resistance.
