Mixtures are claimed which essentially consist of a graft copolymer (A) and (B) and a hard component (C), the latter being composed of copolymers of styrene and / or a-methylstyrene with acrylonitrile. The graft copolymers (A) and (B) are each based on a crosslinked acrylic ester rubber and, on this basis, contain a mixture of styrene and acrylonitrile as a graft shell or graft. They differ only slightly in the chemical composition, but clearly in the particle size of the acrylic ester base used for the grafting. The weight ratio of the graft bases, based on the total mixture, can be in the range from 90: 10 to 35 to 65, and the proportion of the sum of the two graft bases, based on the total mixture, should be about 10 to 35 percent by weight.n n n Mixtures of the 3 components described above are weather-resistant and have a high impact strength with good colorability. The use of such mixtures by the usual methods for thermoplastic processing, such as. B. extrusion or injection molding, results in particular after the previous coloring, in the area of the casting or the weld line practically no different color, so that the most diverse moldings can be used for daily needs or for leisure activities. |
