Abstract
A molding composition based on an impact-modified thermoplastic A selected from ABS, ASA, impact-resistant polystyrene (HIPS) impact resistant polymethyl methacrylate, impact resistant PVC, polycarbonate, polyester carbonate, polyester, polyamide, polyphenylene ether, polyether ketone, polyether sulfone, polysulfone, polyoxyalkylene, polyarylene sulfide and also mixtures thereof containing a matting agent B composed of 30 to 80% by weight of an elastomeric grafting base B1 of 75 to 99.8% by weight of an alkyl acrylate having 1 to 8 carbon atoms in the alkyl radical (B11), 0.1 to 5% by weight of a polyfunctional, crosslinking monomer (B12) and 0.1 to 20% by weight of a monomer containing one or more acidic groups, or 49.9 to 99.9% by weight of one or more dienes (B111), up to 50% by weight of a further ethylenically unsaturated monomer (B112) and 0.1 to 20% by weight of a monomer containing one or more acidic groups (B113), and 20 to 70% by weight of a graft sheath B2 composed of 40 to 99.9% by weight of an aromatic vinyl monomer (B21), up to 49.9% by weight of a polar, copolymerizable, ethylenically unsaturated monomer (B22) and 0.1 to 20% by weight of a monomer containing one or more basic groups (B23), and also a molding composition whose constituents B13 and B113 and B23 are interchanged.
