Method for the production of a copolymer based on vinyl aromatic compounds and conjugated dienes |
摘要 |
The present invention provides a method for the production of a copolymer based on vinyl aromatic compounds and conjugated dienes, in which after polymerization, the copolymers are treated with multi-functional sulfur halides in the presence of a catalyst at temperatures in the range from 20 to 130° C.The copolymers produced according to the present invention demonstrate clearly improved processing characteristics as a result of selective masticating effect and good mechanical properties.
