Abstract: Thermoplastic molding masses based on the copolymerization of styrene and/or alpha -methylstyrene and acrylonitrile, which may be modified to be impact resistant with rubberlike polymers, are made antistatic by adding 0.01 to 1.5 percent by weight of a graft polyol which is a polyhydroxy-polyalkylene polyether modified with styrene-acrylonitrile copolymers.

Abstract: A thermoplastic moulding composition containing from 2 to 60% by weight of a graft copolymer A and from 40 to 98% by weight of a copolymer B. The graft copolymer is prepared by graft copolymerisation of a mixture of a vinylaromatic monomer and acrylonitrile and/or a (meth)acrylic ester ((meth)acrylate) onto an elastomer component containing at least one alkyl acrylate. The elastomer component is prepared using from 0.1 to 20% by weight of at least one diallyl ester of a saturated aliphatic dicarboxylic acid having 4 to 12 carbon atoms. The copolymer B is formed from a vinylaromatic monomer and/or acrylonitrile and/or a (meth)acyrlic ester. The moulding composition may contain conventional additives in effective amounts and is used for the production of mouldings.

Abstract: The invention relates to a weathering-resistant, thermoplastic moulding composition which contains an elastomer phase comprising a core A) and an elastomeric shell B), and a graft shell C) on the core. The elastomer phase A) makes up 95 to 60% by weight, based on A + B, and is built up from 60 to 100% by weight of at least one conjugated diene. It is prepared by polymerisation in aqueous emulsion and agglomeration with the aid of an acrylate dispersion to give particles having a mean diameter in the range from 0.16 to 0.45 mu m (d50 value of the cumulative weight distribution), after which the elastomeric shell B), which makes up from 40 to 5% by weight, based on A + B, is polymerised on. This shell is built up from a mixture of from 60 to 99% by weight of at least one acrylate having 1 to 8 carbon atoms in the alcohol radical and from 0.1 to 5% by weight of a polyfunctional crosslinking monomer. The graft shell C is present in a proportion of from 20 to 90% by weight, based on from 10 to 80% by weight of the sum of the elastomer components A + B, and is built up from a mixture of from 50 to 95% by weight of at least one unsaturated aromatic hydrocarbon having up to 12 carbon atoms, and from 5 to 50% by weight of at least one copolymerisable, monoethylenically unsaturated monomer. The moulding composition may additionally contain from 10 to 150 parts by weight, based on 100 parts by weight of A + B + C, of a hard phase D. The hard phase is formed from a monomer from the group consisting of vinylaromatic monomers and ethylenically unsaturated monomers. Conventional assistants in effective amounts may furthermore be present in the moulding composition. The moulding composition is used to produce mouldings.

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.
