Abstract: Deep black thermoplastic molding compositions having high gloss can be produced by mixing the following components: 90% to 99.5% by weight of one or more styrene copolymers as component A1, or 90% to 99.5% by weight of one or more polymethylmethacrylates (PMMA) and/or polyalkylmethacrylates as component A2, or 90% to 99.5% by weight of one or more polycarbonates (PC) and/or polyester carbonates as component A3, 0.01% to 5% by weight of a pigment black as component B, 0.1% to 1.5% by weight of at least two dyes soluble in the molding composition as component C, 0% to 5% by weight of one or more additives other than components B and C, as component D. These are found to be particularly weathering-resistant.

Abstract: It was found that water-repellent thermoplastic moulding compositions, which comprise a) from 66 to 72% by weight of one or more styrene-acrylonitrile copolymers as component A, b) from 25 to 35% by weight of one or more polyacrylate rubbers as component B, c) from 1 to 5% by weight of one or more fluorine-containing polymer components C, selected from the group of polyvinyliden-difluoride and polyvinyliden-tetrafluoride, d) from 0.05 to 6% by weight of one or more further additives, which are different from C, as component D, where each of the % by weight values is based on the total weight of components A to D and these give a total of 100% by weight, have good replication properties and lead to highly water-repellent surfaces.

Abstract: A process for producing a thermoplastic molding composition comprising: 10% to 40% by weight of a graft copolymer A comprising 50% to 70% by weight, based on A, of a graft base A1 formed from an elastomeric, crosslinked acrylic ester polymer and 30% to 50% by weight of a graft shell A2, 50% to 90% by weight of a hard matrix B formed from copolymers of styrene or α-methylstyrene and acrylonitrile, 0% to 50% by weight of a further graft copolymer C, 0% to 15% by weight of additives D, wherein the reaction for preparation of the acrylic ester polymer A and/or the reaction for preparation of C is conducted in the presence of 0.01 to 4 times the molar amount of sodium carbonate, based on the sum total of the molar amount of initiator used in the preparation of the graft base and graft shell, leads to lower coagulate formation.

Abstract: The invention relates to a thermoplastic composition containing the components A and B and optionally the additional components C and D, the sum of which equals 100 wt. %. The molding compound consists of: a) 60 to 75 wt. % of one or more styrene copolymers A, b) 25 to 40 wt. % of one or more graft copolymers B, c) 0 to 15 wt. % of a rubber C which is different from component B, and d) 0 to 5 wt. % of one or more additives D. The composition contains 0.2 to 3.0 wt. %, based on the total weight of the components A to D, of oligomers, can be readily processed, and leads to scratch-resistant molded parts.
