Claim Text:
1. A thermoplastic composition comprising: from 60 percent to 99 percent by weight of one or more polycarbonates; and from 40 percent to 1 percent by weight of an additive comprising a crosslinked (meth)acrylate polymer, wherein the crosslinked (meth)acrylate polymer comprises at least 99.5 percent by weight derived from methyl methacrylate units, and from greater than zero to less than 0.5 percent by weight derived from one or more multifunctional crosslinking monomers; wherein the crosslinked (meth)acrylate polymer has a volume average particle size in the range of from 185 to 237 nm, and, wherein the crosslinked (meth)acrylate polymer has a Tg from 90° C. and to 115° C. (measured by DSC, second heat); and wherein an article produced from the thermoplastic composition has a hardness of greater than F; and wherein the crosslinked (meth)acrylate polymer is free of chain transfer agents.
