Abstract:
1. A process for the production of moldings via shaping of thermoplastic molding compositions F with reduced formation of deposit on the shaping mold, wherein the thermoplastic molding compositions F comprise an amount of from 3 mg/kg to 75 mg/kg (calculated as the total of the mg of Mg and the mg of Ca per kg of thermoplastic molding composition F and determined by means of atomic emission spectrometry using inductively coupled plasma (ICPAES)) of at least one magnesium compound and/or calcium compound, wherein the molding compositions F comprise, alongside the at least one magnesium compound and/or calcium compound, A) from 20 to 100% by weight of at least one impact-modified vinylaromatic copolymer selected from the group consisting of acrylonitrile-butadiene-styrene copolymers (ABS), acrylonitrile-styrene-acrylate copolymers (ASA), and methacrylate-acrylonitrile-butadiene-styrene copolymers (MABS), B) from 0 to 80% by weight of at least one polycarbonate (PC), and C) from 0 to 60% by weight of further additives conventional in plastics, where each of the percentages by weight is based on the total weight of components A) to C) and the total of the percentages by weight is 100% by weight.
