Abstract

This invention relates to a process for producing polymerisates by anionic polymerization in an inert reaction medium using conjugated dienes and vinylaromatic compounds in the presence of a catalyst, co-catalyst, and randomizer. Further, the invention relates to the polymerisates produced thereby and their uses.
