Patent ID: 6841612

Claim:
A composite plastics composition comprising a particulate crosslinked polymer dispersed within a thermoplastic matrix, wherein; (a) the composite plastics composition comprises 10 to 45 weight percent of the crosslinked polymer, based on the weight of the composite plastics composition, and the crosslinked polymer has a particle size substantially from 0.2 to 1.2 millimeters; (b) the crosslinked polymer comprises 0.1 to 15 weight percent inert filler and 0.1 to 20 weight percent crosslinker, based on the total weight of crosslinked polymer; and (c) the crosslinked polymer is visually differentiable from the thermoplastic matrix, wherein the thermoplastic matrix comprises a mixture of 25 or more weight percent poly(alkyl(meth)acrylate) and up to 75 weight percent impact modifier, based on the weight of thermoplastic matrix and wherein the impact modifier is a multi-stage sequentially-produced polymer containing an elastomeric stage, and wherein the composition is capable of multiple passes through extrusion or molding.
