Abstract: The invention is directed to a method for producing a thermoplastic molding composition comprising at least one styrene polymer and at least one lubricant, selected from fatty acids and fatty acids derivatives, wherein the method encompasses the preparation of a master batch polymer composition, comprising at least one styrene polymer having a melt flow rate (measured according to ASTMD1238, 200° C./5 kg) in the range of 2 to 10 g/10 min; and 10 to 40% by weight, based on the master batch polymer composition, of the lubricant. In particular the styrene polymer is selected from standard polystyrenes (general purpose polystyrene (GPPS)) and high impact polystyrenes(HIPS).

Abstract: A process produces a polymer composition (A) containing a styrene copolymer (a) and an impact modifier (b), comprising a copolymer (b1) as graft base and a graft (b2), where the steps of the process are: (1) providing a crosslinked copolymer (b1) made of: (b11) from 70 to 99.99% by weight of a conjugated diene or acrylate, (b12) from 0 to 29% by weight of another comonomer, (b13) from 0 to 10% by weight of crosslinking monomers, and (b14) from 0.01 to 0.7% by weight of a chain-transfer reagent; (2) applying, to the copolymer (b1), at least one graft (b2) comprising: (b21) from 65 to 95% by weight of a vinylaromatic monomer, (b22) from 5 to 35% by weight of acrylonitrile and/or methacrylonitrile, and (b23) from 0 to 30% by weight of monoethylenically unsaturated monomers, thus providing the impact modifier (b); (3) mixing the styrene copolymer (a) and the impact modifier (b), and thus leads to improved mechanical properties of the polymer composition (A).

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.
