A stabilized halogen containing polymer, preferably poly(vinyl halide), and more preferably poly(vinyl chloride) composition. A preferred polymer composition is a rigid halogenated polymer such as rigid poly(vinyl chloride). The composition contains at least one metal salt selected from the group consisting of at least one carboxylic acid or derivative thereof having at least two carboxyl groups, at least one carboxyl group and at least one hydroxyl group, at least one carboxyl group and at least one mercaptan, and an aromatic carboxylic acid having at least one carboxyl group. The metal salt is most preferably disodium adipate.
稳定的含卤聚合物,最好是聚(卤化
乙烯),更理想的是聚(
氯乙烯)组合物。一种优选的聚合物组合物是硬质卤化聚合物,如硬质聚
氯乙烯。组合物含有至少一种
金属盐,该
金属盐选自至少具有两个羧基、至少一个羧基和至少一个羟基、至少一个羧基和至少一个
硫醇的
羧酸或其衍
生物,以及至少具有一个羧基的芳香族
羧酸。
金属盐最好是
己二酸二
钠。
