Abstract
Glass-fiber-reinforced ABS molding compounds containing up to 5% by weight of a tin-containing organic compound corresponding to formula (I) and/or (II) in which R1 and R2=C1-12 alkyl, R3, R4=C1-18 alkyl, R5=—(CH2)—n, —CH═CH—, —CH═CR1—, X=H, 1 equivalent of an alkali metal, preferably Na or K, ½ equivalent of an alkaline earth metal, preferably Mg or Ca, n=2-8.
