ABSTRACT:
Discrete phase thermoplastic polymers comprising crosslinked acrylate or methacrylate, crosslinked styrene-acrylonitrile, and uncrosslinked styrene-acrylonitrile components can be extruded to provide products having a high surface gloss by the use of an effective amount of a lubricant selected from the group consisting of high molecular weight polymers of ethylene and high molecular weight copolymers of ethylene and vinyl acetate.
