COMPATIBLE MIXTURES OF N-ARYL POLYGLUTARIMIDES WITH STYRENE COPOLYMERS

摘要

Compatible mixtures of styrene copolymers of type SAN (AES, ABS, SAN) with polyglutarimides, characterized in that they are prepared by imidization of poly(meth)acrylates and/or poly(meth)acrylic acid with amides of formula X-Z-NHR where X = H, hydrocarbyl or, when , a -NHR radical or a -Y-C0-NHR radical; R = aryl; , . -C 6H4-SO2. The mixtures of SAN copolymers with N-aryl polyglutarimides having a Tg of at least 140.degree.C are claimed as new mixtures.
