Abstract: PCT No. PCT/EP97/01875 Sec. 371 Date Oct. 8, 1998 Sec. 102(e) Date Oct. 8, 1998 PCT Filed Apr. 15, 1997 PCT Pub. No. WO97/39062 PCT Pub. Date Oct. 23, 1997Molding materials (F) which are suitable for the production of shaped articles having reduced surface gloss and are based on polymers or polymer blends (P), preferably ASA polymers and/or styrene/acrylonitrile copolymers, contain a sufficient amount of a dull graft copolymer (A) admixed as dulling agent, which was prepared by one-stage or multistage graft copolymerization of monomers forming the hard shell onto an elastomeric acrylate polymer, the graft copolymerization being carried out to a conversion of more than 15% by thermal or free radical mass or solution polymerization.

Date Jan. 16, 1997Graft copolymers (P1) contain, in any desired sequence, at least (P1.1) a hard segment having a glass transition temperature of at least 11 DEG C., which contains at least one vinylaromatic monomer as the monomer or as one of two or more monomers copolymerizable with one another and a crosslinker component comprising at least dihydrodicyclopentadienyl acrylate as a crosslinking agent having two or more functional groups of different reactivity and at least one crosslinking agent having two or more functional groups of the same reactivity, and (P1.2) a soft segment having a glass transition temperature of not more than 10 DEG C., which contains at least one acrylate as the monomer or as one of two or more monomers copolymerizable with one another, and blends and thermoplastic materials contain said graft copolymers.
