Abstract: The moulding composition contains, in each case based on A + B, from 80 to 55% by weight of a hard matrix A comprising a copolymer of at least 95% by weight of a vinyl aromatic monomer a11 having 8 to 10 carbon atoms and at least one comonomer a12 in a proportion of from 0.1 to 5% by weight, based on A, from 45 to 20% by weight of a soft phase B which is uniformly distributed in the hard matrix and has a mean particle diameter d50 (volume average) of from 3.5 to 9 mu m and is obtainable by polymerisation of the mixture of monomers a11 and a12 in the presence of an elastomer (rubber) with subsequent isolation of the target product, the comonomer a12 having the formula I in which X is an-OR , COOR or -CONHR radical and R is hydrogen or methyl and R and R are each an alkyl radical having 1 or 2 to 10 carbon atoms and carrying at least 1 OH group or an epoxide group or at least one other polar group.

Abstract: The moulding composition contains a copolymer of a) styrene, b) optionally acrylonitrile and c) an N-substituted amide of methacrylic acid, the monomers being present in amounts of from 1 to 95% by weight of a), up to 40% by weight of b) and from 98 to 5% by weight of c), and the monomer c) used being the methacrylamide of the formula … … in which R is a primary, secondary or tertiary alkyl radical, cycloalkyl radical, aryl radical or aralkyl radical having 1 to 12 carbon atoms, with the proviso that, if the alkyl radical is methyl or isopropyl, the copolymers have a styrene content of less than 75% by weight.

Abstract: Moulded compositions comprising a matrix of impact-modified polystyrene and rubber included in the form of discrete particles contain at least 50% by weight of polystyrene A and an effective amount of up to 50% by weight of a graft rubber B. The graft rubber B comprises from 40 to 95% by weight of a rubber-elastic graft core b1 and from 5 to 60% by weight of a graft shell b2, namely from 5 to 50% by weight of a first graft shell b21 comprising styrene and from 50 to 95% by weight of a second graft shell b22 comprising from 60 to 90% by weight of styrene and from 10 to 40% by weight of acrylonitrile, the amounts of A and B, b1 and b2, b21 and b22 and styrene and acrylonitrile in each case adding up to 100% by weight.

Abstract: A flameproofed thermoplastic moulding composition comprising (A) from 30 to 90 % by weight of at least one halogen-free, thermoplastic styrene (co)polymer and (B) from 10 to 70 % by weight of cellulose, starch and/or sawdust particles coated with from 30 to 300 % by weight, based on their weight, of melamine phosphate, as a further, preferably the only, halogen-free constituent.
