Abstract:
1. A particulate composite plastics composition comprising a blend of separately formed polymer particles of different compositions, comprising; a) 55 to 90 weight percent of at least one thermoplastic polymer in the form of particles as the matrix polymer; wherein said thermoplastic polymer is reversibly deformable, wherein the thermoplastic matrix polymer is selected from the group consisting of alkyl (meth)acrylate polymers and copolymers, aerylonitrile-butadiene-styrene (ABS) terpolymers, acrylonitrile-styrene-acrylic (ASA) copolymers, polycarbonates, polyesters, poly(butylene terephthalate), poly(ethylene terephthalate), MBS copolymers, high impact polystyrene (HIPS), acrylonitrile/acrylate copolymers, acrylonitrile/methyl methacrylate copolymers, impact modified polyolefins and impact modified polyvinyl chloride (PVC), or mixtures thereof, b) 10 to 45 weight percent of at least one crosslinked polymer composition in the form of particles having a particle size of from 0.2 to 1.2 millimeters; comprising 0.1 to 15 weight percent inert filler and 0.1 to 20 weight percent crosslinker, based on the total weight of crosslinked polymer;
