    • A process for producing impact-resistant moulding compositions, which is characterised in that a monomer mixture comprising 90 to 20 parts by weight of an aromatic monoalkenyl compound, 10 to 50 parts by weight of an ethylenically unsaturated nitrile, 0 to 30 parts by weight of other copolymerisable compounds is polymerised by a radical mechanism in the presence of 15 to 50 parts by weight, per 100 parts by weight of monomers, of a soluble, gel-free butadiene polymer, and in the presence of 50 to 200 parts by weight, per 100 parts by weight of monomers, of a solvent, wherein the solvent is selected from the group comprising an aliphatic (C1-C8) or cycloaliphatic alcohol, ketone, ether, ester, nitrile (A) or mixtures thereof or a mixture of (A) with an aliphatic (C4-C10), cycloaliphatic or aromatic hydrocarbon (B) in an A:B weight ratio of 100:0 to 30:70, and the polymerisation is conducted as far as a polymer content of the total mixture of 30 to 70% by weight, with thorough mixing and optionally with the subsequent addition of a regulator and initiator, so that the isolated thermoplastic moulding composition contains 20 to 40% by weight of butadiene polymer.
    • 一种耐冲击成型组合物的制造方法,其特征在于,含有90〜20重量份芳香族单链烯基化合物,10〜50重量份烯属不饱和腈,0〜30重量份其它 可共聚合的化合物通过自由基机理在每100重量份单体,每100重量份单体,可溶性,无凝胶的丁二烯聚合物存在下共聚合15至50重量份,并且在50至200重量份的存在下,每100份 单体重量的溶剂,其中溶剂选自脂族(C1-C8)或脂环族醇,酮,醚,酯,腈(A)或其混合物或(A)与 脂族(C 4 -C 10),脂环族或芳族烃(B),其A:B重量比为100:0至30:70,并进行聚合,只要总混合物的聚合物含量为30-70% 重量,充分混合和选择 随后加入调节剂和引发剂,使得分离的热塑性模塑组合物含有20至40重量%的丁二烯聚合物。
