Abstract:
A molding material (F) for the production of shaped articles having reduced surface gloss, and based on polymers or polymer blends (P), which contain, in admixed form and in sufficient amount, a molding composition (A) based on a graft copolymer as a dulling agent, wherein the molding material (A) was prepared by one-stage or multistage polymerization of a mixture (AM) containinga) one or more olefinically unsaturated monomers (A1m) which form the graft shell (A1) and form a polymer or copolymer having a glass transition temperature of at least +20.degree. C., andb) as the grafting base, a prepared acrylate polymer (A2) which is dissolved or swollen in the monomer or monomers (A1m) and has a glass transition temperature of less than -20.degree. C.,at least the first stage of the polymerization of the mixture (AM) being performed, to a conversion of more than 15% by weight of the monomers, by thermal or free radical mass or solution polymerization.
