Patent ID: 7592394

Claim:
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; wherein said crosslinked polymer is visually differentiable from the thermoplastic matrix, wherein said crosslinked polymer particles are allyl ester polymer, epoxy resin, or crosslinked polymer formed from a monomer mixture comprising vinylaromatic monomers, (meth)acrylic monomers, or a mixture thereof; wherein said particulate composite plastics composition is capable of multiple passes through extrusion or injection molding; and wherein said particulate composite plastics composition is in the form of pellets, beads, powder, granules or chips.
