Abstract: Thermoplastic molding materials contain a copolymer A and a graft copolymer B. The copolymer A is a hard component comprising one or more copolymers of styrene and/or alpha -methylstyrene with from 20 to 40% by weight of acrylonitrile. The graft copolymer B comprises one or more crosslinked acrylate polymer with a mean particle size of 0.5-0.8 mu m (d50 value of the cumulative mass distribution), a particle distribution, expressed by the ratio in the range Q>/=0.6, and a glass transition temperature Tg below 0 DEG C. A mixture of styrene and acrylonitrile in a weight ratio from 88:12 to 65:35 is grafted onto this rubber.

Abstract: Thermoplastic molding materials based on styrene polymers which have been made impact-resistant and on polyphenylene ethers, wherein the particles of the soft component of the styrene polymer which has been made impact-resistant have a mean diameter of more than 1 micron, and wherein the proportion of particles which have a diameter of less than 0.6 micron is not less than 40% by weight and the proportion of particles which have a diameter of from 0.6 to 3 microns is less than 3% by weight.

Abstract: Prepn. of block copolymers from a polymer block (a) from anionic-polymerisable monomer (a) and one or two polymer blocks (B) from radical-polymerisable monomer (b), is described. The process comprises (1) coupling of block (A) with one or two end alkali metal-carbon bonds with an azo cpd. of formula X-(CH2)n-C(R1R2)-N N-C(R1R2)- - (CH2)n-X (I) where X is Cl or Br, R1 and R2 are 1-20C aliphatic, cycloaliphatic or aromatic gps.; n is 0-5) (2) addn. of (b) and heating to decompose the coupling prod. and give a block (A) with one or two radical chain ends, and (3) polymerisation of blocks (B) or to one or both chain ends. Molar ratio of alkali metal in (A) to halogen in (I) is pref. 1:1. Impact-resistant copolymers, e.g. of SAN or ABS type, may be obtd. Yield and mechanical properties of the prodn. are improved by use of (I) in place of azodinitriles.
