Abstract

Anionic polymerization is used for the preparation of reaction mixtures comprising homopolymers, copolymers or block copolymers, and of homopolymers, copolymers and block copolymers which comprise acrylates or methacrylates or acrylates and methacrylates, wherein olefinically unsaturated compounds which are not acrylate or methacrylate derivatives are employed as solvent or as solvent component.
