Abstract

The invention relates to processes for the production of moldings via shaping of thermoplastic molding compositions F with reduced formation of deposit on the shaping mold, and it is essential to the invention that the thermoplastic molding compositions F comprise an amount of from 0 mg/kg to 100 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 magnesium compounds and/or calcium compounds; the invention further relates to the use of molding compositions F in the inventive processes, and also to moldings which can be produced by the inventive processes.
