Abstract (en)

[origin: WO9950348A1] The inventive molding material contains components A to C and optionally D; a: 20 to 94 wt. % of a hard component comprised of one or more copolymers of styrene and/or alpha -methyl styrene with acrylonitrile, whereby the proportion of acrylonitrile is equal to 10 to 50 wt. %, as component A; b: 5 to 70 wt. % of a graft copolymer B comprised of b1: 10 to 90 wt. % of at least one rubber elastic, particle-shaped graft base having a glass transition temperature of less than 0 DEG C, as component B1, and b2: 10 to 90 wt. % of at least one graft coating comprised of a copolymer of styrene and/or alpha -methyl styrene with acrylonitrile, whereby the proportion of acrylonitrile is equal to 10 to 50 wt. %, as component B2; c: 0.1 to 10 wt. % of at least one triple-block copolymer of formula X-Y-X having a centrally located block Y comprised of propylene oxide units with an average molecular weight ranging from 2,000 to 4,000 and terminal blocks X comprised of ethylene oxide units whose average proportion in the triple-block copolymer is equal to 2 to 35 wt. %, as component C, whereby the total weight of components A to C amounts to 100 wt. %; d: 0 to 10 wt. %, with regard to the total weight of components A to C, of additional, common auxiliary agents and fillers as component D.
