    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: The invention relates to a vinyl aromatic/diene-block copolymer A, obtained by an anionic polymerization of a monomer composition, comprising: Al: 60-95 wt.-% of at least one vinyl aromatic monomer, and A2:5-40 wt.-% of at least one diene monomer, wherein the vinyl aromatic/diene-block copolymer A in total comprises less than 10 parts per million (ppm) of acetaldehyde, methacrolein and styrene based on the total amount of vinyl aromatic/diene-block copolymer A; the vinyl aromatic/diene-block copolymer A has improved orgnoleptic properties and is in particular suitable for producing food packaging materials.
