Abstract
Abstract Thermoplastic polymer mixture with a high surface gloss on the basis of: a 50-95 wt. % of a.1 20-90 wt. % of a copolymer of styrene and/or α-methyl-styrene with acrylonitrile with an acrylonitrile content of 18-27 wt. %, the copolymer having a fluidity of 3-20; a.2 5-60 wt. % of a copolymer of styrene and α-methyl-styrene with acrylonitrile with an acrylonitrile content of 25-40 wt. %, the copolymer having a fluidity of at least 25; a.3. 0-30 wt. % of a polyacrylate compound; b 5-50 wt. % of b.1 a substantially saturated rubber and b.2 chlorinated polyethylene. The thermoplastic polymer mixture not only has a high surface gloss, but also the flow of the mixture has been improved substantially. As a result, the mixture has excellent processing characteristics.
