Verfahren zur Herstellung kautschukmodifizierter Formmassen

摘要

The invention concerns a process for preparing rubber-modified moulding compounds, characterized in that: a1) a mixture (A) comprising acrylate or methacrylate derivatives or acrylate and methacrylate derivatives and a solvent, optionally containing olefinically unsaturated compounds which are not acrylate or methacrylate derivatives, is anionically polymerized; or that a2) acrylate or methacrylate derivatives or acrylate and methacrylate derivatives are sequentially anionically polymerized to form block copolymers in the presence of a solvent which optionally contains olefinically unsaturated compounds; and b) the reaction mixture obtained according to a1) or a2) or a1) and a2) is subjected to a radically initiated polymerization process, optionally after the addition of further unsaturated compounds.
