Abstract
The invention relates to a thermoplastic molding compound containing: a) 50 to 85 parts of one or more terpolymers based on acrylnitril, alpha-methylstyrene, and styrene as component A, said terpolymers consisting of: 5 to 30 wt. % styrene, 15 to 35 wt. % acrylnitril, 50 to 70 wt. % alpha-methylstyrene, and 0 to 5 wt. % additional copolymerizable monomers, b) 15 to 50 parts of one or more impact-modifying graft rubbers with an olefinic double bond in the rubber phase as component B, c) 0 to 45 parts of one or more copolymers based on styrene and acrylnitril as component C, said copolymers consisting of: 71 to 81 wt. % styrene, 29 to 19 wt. % acrylnitril, and 0 to 5 wt. % additional copolymerizable monomers, and optionally additives and fibrous and/or particulate fillers. The thermoplastic molding compound leads to a reduced yellowing of the produced molded body.
