Abstract

The invention relates to graft copolymers—based on non-cross-linked acrylate soft phases from which styrenic monomers are grafted—with a defined micro-structure, having a high transparency, toughness and weather resistance (UV-stability), a process for their preparation and their use, and also to polymer blends comprising said graft copolymers and styrenic polymers, and shaped articles produced therefrom and their use.
