Abstract: Compatible mixtures of styrene copolymers of type SAN (AES, ABS, SAN) with polyglutarimides, characterized in that the polyglutarimides are prepared by imidization of poly(meth)acrylates and/or poly(meth)acrylic acid with amides of formulaX--Z--NHRwhereX=H, hydrocarbyl or, when ##STR1## a --NHR radical or a --Y--CO--NHR radical; R=aryl; ##STR2## --C.sub.6 H.sub.4 --SO.sub.2. The mixtures composed of SAN copolymers and N-aryl polyglutarimides having a Tg of at least 140.degree. C. are claimed as new mixtures.
