Abstract: A thermoplastic molding material consists of a polycarbonate A and a graft copolymer B, the latter consisting of an elastomer (rubber) (b1) and a shell (b2) grafted onto the elastomer. The elastomer (b1) contains, as copolymerized units, from 35 to 100% by weight of a diene from the group consisting of the conjugated dienes of 4 to 5 carbon atoms, and can contain, as copolymerized units, from 0 to 65% by weight of a monomer from the group consisting of the alkyl acrylates or alkyl methacrylates, where alkyl is of 1 to 8 carbon atoms. The shell (b2) is obtained in a conventional manner by successive polymerization of the monomers constituting the shell, in two process steps, in the presence of the elastomer (b1); in a first process step, from 10 to 90% by weight of a mixture of a vinylaromatic hydrocarbon and one or more ethylenically unsaturated monomers which differ from the said hydrocarbon, in a weight ratio of from 90:10 to 60:40, are first incorporated as copolymerized units, followed by the polymerization of from 90 to 10% by weight of a monomer from the group consisting of the alkyl acrylates or of the alkyl methacrylates, where alkyl is of 1 to 8 carbon atoms. The molding material is used for the production of shaped articles.

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: The invention relates to a self-extinguishing, thermoplastic moulding composition comprising A) ABS (built up in three parts, namely from rubber, graft shell + separate hard matrix), B) A halogen-containing organic compound (flameproofing agent), C) a metal or non-metal containing compound (synergist), D) a stabiliser, and E) a halogen-free component, based on novolaks which are obtainable from aldehydes of the formula (I> R -CHO in which R = H, C1-C10-alkyl, cycloalkyl or C6-C12-aryl or -aryl-C1-C3-alkyl, and phenols or mixtures of phenols, where the mixtures contain at least two monosubstituted phenols and the substituents may be alkyl radicals having 1 to 8 carbon atoms or CN, and which have number average molecular weights of 500 to 2000, where the novolaks used are those which have been modified first by introduction of at least one side group containing an ethylenic double bond and bonded via an oxygen atom of the novolak, and where e1) from 10 to 90% by weight of the thus-modified novolak (as graft base) and e2) from 90 to 10% by weight of a mixture of styrene and acrylonitrile (graft shell) have been grafted on. The moulding composition according to the invention is advantageously used for the production of mouldings.

Abstract: The invention relates to a moulding composition containing a hard matrix A essentially comprising a polymer of a vinylaromatic monomer in a proportion of from 70 to 95 % by weight, based on the moulding composition of A+B, and a soft phase B, distributed therein, in a proportion of from 5 to 30 % by weight, based on the moulding composition of A+B, which has a mean particle size in the range from 0.1 to 1.5 mu m (number average). The soft phase is a graft copolymer comprising the vinylaromatic monomer of the polymer building up the hard matrix and an elastomeric styrene-butadiene two-block copolymer. The vinylaromatic monomer for building up the hard matrix A comprises ring-alkylated styrenes such that the soft phase B contains more than 70% (number average) of shell particles.
