Zusammenfassung: | Process for obtaining mouldable masses, characterized in that in a first stage, 10-35 parts by weight of a mixture of 50-90% by weight of styrene, methyl methacrylate or mixtures thereof and 50-10% by weight weight of acrylonitrile and/or esters of acrylic acid, in a polybutadiene latex or a butadiene copolymer with up to 30% by weight of styrene, whose particles have a size of 0.05-0.19 μ, polymerized by grafting in the presence of a radical catalyst, the amount of the latex being sized so that 90-65 parts by weight of polymer are present; in a second stage, to this graft-latex polymer is added a latex of a copolymer of 50-90% by weight of styrene and/or α -methylstyrene and 50-10% by weight of acrylonitrile and/or an amount of acrylic acid in an amount such that there are present 80-10 parts by weight of copolymer; in a third step, the polymers are precipitated together by the addition of an electrolyte; in a fourth stage, it is separated and dried; and in a fifth step, the mixture is melted and 10-80 parts by weight of a polycarbonate, the fusions are combined and mixed homogeneously.
