Patent ID: 7683131

Claim:
A moulding composition, comprising a) from 50 to 99.9% by weight of a matrix composed of a thermoplastic polymer and b) from 0.1 to 50% by weight of a matting agent in the form of a (meth)acrylate copolymer dispersed in the matrix, wherein the matting agent is a (meth)acrylate copolymer which has been prepared from the following monomers, b1) from 50 to 90% by weight of methyl methacrylate b2) from 10 to 50% by weight of ethyl acrylate and/or butyl acrylate b3) from 0.01 to 5% by weight of a crosslinking monomer and/or graft-linking agent having two or more ethylenically unsaturated radicals capable of free-radical polymerization, where the entirety of the constituents b1), b2), and b3) gives 100% by weight, and the glass transition temperature T mg of the matting agent is at least 20° C.
