    摘要: The invention relates to light-scattering polystyrene molding compounds comprising40-99.9 weight % of a (optionally impact-strength-modified) polymeric matrix phase comprised of at least 50 weight % styrene and or substituted styrenes, or a mixture thereof; and0.1-60 weight % of scattering bodies comprising a copolymer comprised of:p1) 20-89.5 parts by weight (pbw) methyl methacrylate, ethyl methacrylate, or a mixture thereof;p2) 10-80 pbw of at least one monomer of formula (I) ##STR1## where R.sub.1 represents a C.sub.3-24 alkyl group; and p3) 0.5-10 pbw of at least one crosslinking monomer with two or more ethylenically unsaturated, radically polymerizable groups; andp4) 0-10 pbw of additional ethylenically unsaturated monomers which are radically copolymerizable with (p1), (p2), and (p3); wherein the sum of the amounts of the monomers (p1), (p2), (p3), and (p4) is 100 pbw.
