    Abstract: The present invention provides a functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer which is obtained from the following layers by emulsion graftlinking polymerization: an inner layer comprising polybutadiene or an aromatic vinyl compound-butadiene copolymer; a middle layer comprising an aromatic vinyl compound--an alkyl acrylate copolymer; and an outer layer comprising an alkyl acrylate--a functional group-containing vinyl compound copolymer. The functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer can be incorporated into a PC/PBT alloy as an impact modifier, thus the impact strength of the modified alloy composition at room temperature and low temperatures can be increased effectively.

    Abstract translation: 本发明提供了通过乳液接枝聚合从以下层获得的含官能团的丙烯酸烷基酯 - 丁二烯 - 芳族乙烯基化合物共聚物:包含聚丁二烯或芳族乙烯基化合物 - 丁二烯共聚物的内层; 包含芳族乙烯基化合物 - 丙烯酸烷基酯共聚物的中间层; 以及包含丙烯酸烷基酯 - 含官能团的乙烯基化合物共聚物的外层。 含有官能团的丙烯酸烷基酯 - 丁二烯 - 芳族乙烯基化合物共聚物可以作为抗冲改性剂加入到PC / PBT合金中,从而可以有效地提高改性合金组合物在室温和低温下的冲击强度。
