Abstract
Blends of a polycarbonate resin and an interpolymer modifier comprising crosslinked (meth)acrylate, crosslinked styrene-acrylonitrile, and uncrosslinked styrene-acrylonitrile polymeric components are disclosed. The blends have improved processing as compared to the processing characteristics of the polycarbonate resin alone and are impact resistant. They are more weather resistant than blends of the polycarbonate resin and ABS graft copolymers.
