The present invention provides a method for the production of a copolymer based on - vinyl aromatic compounds and conjugated dimes, in which after polymerisation 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 invention demonstrate clearly improved processing characteristics as a result of selective masticating effect and good mechanical properties.
