    Abstract: Mouldings made of thermoplastic moulding masses contain (A) 30 to 99 wt %, relative to the total weight of the moulding mass, of a thermoplastic polymer, comprising, relative to (A): (a1) 50 to 100 wt % of a styrene compound of general formula (I), in which R?1 and R2¿ stand for hydrogen or C¿1?-C8 alkyl, or a (C1-C8-alkyl)ester of acrylic or methacrylic acid, or mixtures of the styrene compound and of the (C1-C8-alkyl)ester of acrylic or methacrylic acid; (a2) 0 to 40 wt % acryl nitrile or methacryl nitrile or their mixtures; and (a3) 0 to 40 wt % of one or several other monoethylenically unsaturated monomers different from (a2); (b) 1 to 70 wt %, with respect to the total weight of the moulding mass, of a graft polymer comprising, relative to (B): (b1) 30 to 90 wt % of a rubber-elastic grafted core made of a polymer with a glass transition temperature below 0 °C and obtained by copolymerising (b11) 50 to 99.99 wt %, with respect to (b1), of a (C1-C10-alkyl)ester of acrylic acid; (b12) 0.01 to 10 wt % of a polyfunctional, cross-linking monomer; and (b13) 0 to 40 wt % of one or several others monoethylenically unsaturated monomers different from (b11); and (b2) 10 to 70 wt % of a grafted sheath which contains, relative to (b2): (b21) 50 to 100 wt % of a styrene compound of general formula (I), in which R?1 and R2¿ stand for hydrogen or C¿1?-C8-alkyl; or a (C1-C8-alkyl)ester of acrylic acid or methacrylic acid; or mixtures of the styrene compound and of the (C1-C8-alkyl)ester of acrylic or methacrylic acid; (b22) 0 to 40 wt % acryl nitrile or methacryl nitrile or their mixtures; and (b23) 0 to 40 wt % of one or several other monoethylenically unsaturated monomers.

    Abstract: The invention relates to thermoplastic moulding materials containing a mixture of (A) between 30 and 69 wt. %, in relation to the sum of the constituents (A), (B) and (C), of a methylmethacrylate polymer, (B) between 30 and 69 wt. %, in relation to the sum of the constituents (A), (B) and (C), of a copolymer that can be obtained by the polymerisation of a vinylaromatic monomer and a vinylcyanide, and (C) between 1 and 40 wt. %, in relation to the sum of the constituents (A), (B) and (C), of a graft copolymer that can be obtained from (C1) between 60 and 90 wt. %, in relation to (C), of a core, (C2) between 5 and 20 wt. %, in relation to (C), of a first graft envelope consisting of a vinylaromatic monomer, an alkylmethacrylate and optionally a cross-linking monomer, and (C3) between 5 and 20 wt. %, in relation to (C), of a second graft envelope consisting of an alkyl(meth)acrylate polymer, on the proviso that the quantitative ratio of (C2) to (C3) is between 2:1 and 1:2. The invention is characterised in that the average particle size D50 of the core (C1) is between 50 and 250 nm, the average particle size D90 of the core (C1) is between 60 and 1000 nm, the average particle size D90 of the core (C1) being larger than the average particle size D50 of the core (C1), by a factor between 1.15 and 20, and the core (C1) can be obtained by the polymerisation of a monomer mixture comprising (C11) between 65 and 89 wt. %, in relation to (C1), of a 1,3-diene, (C12) between 10 and 34.9 wt. %, in relation to (C1), of a vinylaromatic monomer, and (C13) between 0.1 and 5 wt. %, in relation to (C1), of an agglomeration polymer. The invention also relates to a method for producing said moulding masses, to the use thereof, and to the moulded bodies obtained therefrom.

    Abstract: A process for preparing impact-modified styrene polymers (HIPS) omprises anionic polymerization of styrene in the presence of a rubber in one or more polymerization reactors in succession. The rubber is prepared in solution in an immediately upstream process. The heat of polymerization is utilized to remove the solvent for the rubber, this solvent having a boiling point lower than those of styrene and ethylbenzene, from at least one of the polymerization reactors via distillation with distillative cooling, and the solvent is reintroduced into the process of rubber preparation.
