Abstract: ABS thermoplastic molding compositions for the preparation of blow molded articles in the automotive and household sector comprising (A) 30 to 40 wt.-% ABS graft rubber copolymer, (B) 25 to 35 wt.-% alpha-methylstyrene/acrylonitrile copolymer, (C) 30 to 40 wt.-% styrene/acrylonitrile copolymer, (D) 0.05 to 0.50 wt.-% homo- or copolymer comprising monomer structure units with a C3-C6-alkyleneoxide side chain having an epoxy terminal group or with a modified, functionalized C3-C6-alkyleneoxide side chain, and (E) 0 to 5 wt.-% further additives. Component (D) is preferably polyglycidylmethacrylate.

Abstract: The invention relates to thermoplastic molding compositions (T) comprising 10 to 99% by weight, based on the total weight of the molding composition (T), of at least one type of recycled polymer material (A), containing 20 to 100% by weight, based on recycled material (A), of recycled acrylonitrile-butadiene-styrene copolymer (A1); up to 80% by weight of at least one recycled styrene-acrylonitrile copolymer (A2); up to 10% by weight of recycled polymeric impurities (A3), different from (A1) and (A2); 0.1 to 30% by weight, based on the total weight of the molding composition (T), of at least one graft copolymer (B), different from (A); 0.1 to 18% by weight, based on the molding composition (T), of block copolymer (C); and optionally up to 89.8% by weight of further polymer component (D), different from (A), (B) and (C); optionally up to 30% by weight of filler and/or reinforcing agent (E); and optionally up to 30% by weight of further additive (F).

Abstract: Thermoplastic molding composition—having an improved fatigue resistance, balanced mechanical properties and a high ductility for applications demanding high endurance under cyclic loading conditions—comprising 25 to 45 wt.-% ABS graft copolymer (A), consisting of 50.5 to 55 wt.-% of a graft sheath (AN content 30.5 to 34 wt.-%) (A2) and 45 to 49.5 wt.-% of a graft substrate (A1), and 55 to 75 wt.-% SAN copolymer (B) (AN content (30 to 33 wt.-%, melt flow rate 30 to 36 g/10 min (220° C./10 kg)).

Abstract: The invention relates to a process for producing graft copolymers based on acrylonitrile-butadiene-styrene copolymers (ABS), wherein the graft copolymers may be dewatered particularly readily after production and precipitation and have a low residual moisture content after centrifugation. The invention further relates to a process for producing thermoplastic molding materials using the thus obtained ABS graft copolymers.
