Abstract

A pigmented high-impact plastic comprising by weight about PA1 (a) 40 to 99.9% of ABS polymer or polyamide, and PA1 (b) 0.1 to 60% by weight of a pigment or filler preparation made up of PA2 30 to 70% by weight of pigment or filler, and PA2 70 to 30% by weight of a polymer comprising units of the formula (CHR--CH.sub.2).sub.n where R is hydrogen or methyl and n is a number from about 50 to 40,000. The pigment or filler preparation is made by mixing an aqueous suspension of the pigment or filler with an aqueous suspension of the polymer comprising (CHR--CH.sub.2) units and drying the joint suspension. The plastics so pigmented are characterized by high impact strength, often greater than the unpigmented plastics.
