    摘要: Preparation of rubber-modified molding compositions comprises a1) anionic polymerization of a mixture (A) comprising acrylate derivatives or methacrylate derivatives or acrylate derivatives and methacrylate derivatives and a solvent, if desired comprising olefinically unsaturated compounds which are not an acrylate derivative or a methacrylate derivative, or a2) sequential anionic polymerization of acrylate derivatives or methacrylate derivatives or acrylate derivatives and methacrylate derivatives in the presence of a solvent which, if desired, comprises olefinically unsaturated compounds to give block copolymers, and b) subjecting the reaction mixture obtained in a1) or a2) or a1) and a2) to a free-radical-initiated polymerization, if desired after the addition of unsaturated compounds.
