Abstract: The present invention relates to an acrylic process aid useful in vinyl foam extrusion. The process aid is an acrylic copolymer containing from 50 to 79 weight percent of methyl methacrylate monomer units and has a Tg of less than 90° C., preferably less than 70° C., and more preferably less than 65° C. PVC and CPVC foams containing this acrylic process aid fuse faster at the same temperature, or fuse in the same time at lower temperatures than foam formulations currently used.

Abstract: The invention relates to an acrylic copolymer additive useful as a process aid in highly filled polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) composites. The acrylic additive is especially useful in highly filled PVC flooring tiles, rolled flooring, pipe and siding. The acrylic copolymer additive contains from 50 to 79 weight percent of methyl methacrylate monomer units, and has a Tg of less than 90° C.
