Abstract: The invention relates to a process for preparing an impact-modified plastic based on grafted crosslinked rubber particles, and also to an impact-modified plastic obtainable by the process. To prepare the impact-modified plastic, (a) particles of a crosslinked rubber are produced from a first monomer mixture which has a content of

Abstract: Elastomeric block copolymers comprising at least one hard block A composed of styrene monomers and at least one elastomeric block (B/A) composed of styrene monomers and dienes, the glass transition temperature Tg of the block A being more than 25° C. and that of block (B/A) being less than 25° C. and the phase volume ratio of block A to block (B/A) being chosen so that the proportion of the hard phase in the total block copolymer is from 1 to 40% by volume and the amount by weight of the diene is less than 50% by weight, and the relative proportion of 1,2 linkages of the polydiene, based on the sum of 1,2- and 1,4-cis/trans linkages, being below 15%, are prepared by anionic polymerization by means of a lithium alkyl in a nonpolar solvent in the presence of a soluble potassium salt and are used for the production of shaped articles.

Abstract: Polymer mixtures compriseP1) from 1 to 85% by weight of an elastomeric block copolymer which has been built up from hard blocks S made from vinylaromatic monomers and from random soft blocks B/S made up from dienes and from vinylaromatic monomers, and which contains at least the block structure S-B/S-S, where the diene content is less than 50 percent by weight and the proportion of the soft phase formed from the blocks B/S is at least 60 percent by weight, based in each case on the entire block copolymer,P2) from 5 to 89% by weight of a block copolymer differing from P1) and made from vinylaromatic monomers and from dienes,P3) from 10 to 94% by weight of glass-clear or impact-modified polystyrene or mixtures thereof, andP4) from 0 to 84% by weight of other additives,where the total of components P1) to P4) is 100%.

Abstract: Graft copolymers are obtainable by (A) polymerization of from 25 to 60% by weight of a mixture con sisting essentially of (a1)from 70 to 99.9% by weight of a C1-C18-alkyl ester of acrylic acid, where the alkyl radical may be monosubstituted by phenyl or phenoxy, (a2)from 0.1 to 10% by weight of a polyfunctional monomer and (a3)from 0 to 29.9% by weight of an ethylenically unsaturated monomer which differs from (a1) and (a2) and is copolymerizable therewith in the presence of from 5 to 25% by weight of a crosslinked silicone rubber and (B) polymerization of from 30 to 50% by weight of a mixture con sisting essentially of (b1)from 50 to 100% by weight of a styrene compound of the general formula (I) I where R1 and R2 independently of one another are each hydrogen, C1-C8-alkyl or C1-C4-alkyl-monosubstituted, C1-C4-alkyl-disubstituted or C1-C4-alkyl-trisubstituted phenyl, and/or of a C1-C8-alkyl ester of methacrylic or acrylic acid, and (b2)from 0 to 50% by weight of a monomer selected from the group consisting of methacrylonitrile, acrylonitrile, methacrylic acid, acrylic acid, maleic anhydride, maleimide N-substituted by C1-C4-alkyl, vinyl esters of aliphatic C2-C8-carboxylic acids, acrylamide and vinyl methyl ether, in the presence of the graft copolymer (A).
