Masa de moldeo, que contiene un agente de mateado |
摘要 |
The invention relates to a moulding composition, comprising a) 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, characterized in that the matting agent is a (meth)acrylate copolymer which has been prepared from the following monomers, b1) from 50 to 95% by weight of methyl methacrylate b2) from 5 to 50% by weight of C1-C6-alkyl acrylates b3) from 0.01 to less than 0.5% by weight of a crosslinking monomer and/or graft-linking agent having two or more ethylenically unsaturated radicals capable of free-radical polymerization, b4) from 0 to 20% by weight of one or more other, non-crosslinking ethylenically unsaturated monomers capable of free-radical polymerization, where the entirety of the constituents b1) and b2) and, where appropriate, b3) and/or b4) gives 100% by weight, and the glass transition temperature Tmg of the matting agent is at least 20� C. |
