A polystyrenic resin composition comprising (A) a styrenic polymer composition containing (a) 1 to 99 % by weight of a polystyrenic resin having the syndiotactic configuration, (b) 1 to 99 % by weight of a polyamide resin, (c) 0.1 to 10 % by weight of a compatibilizer which is compatible with component (a) and has a polar group reactive with component (b), and (d) 0 to 50 % by weight of a rubbery elastomer and/or a modified rubbery elastomer, (B) specific amounts of a copper compound and an iodine compound, and optionally, specific amounts of (C) a phenolic compound, (D) N,N'-hexamethylenebis(3,5-di-t-butyl-4-hydroxyhydrocinnamide), (E) an ester of thiodipropionic acid or a derivative thereof, (F) a copper inhibitor, and (G) inorganic filler; and a molded article prepared from the polystyrenic resin composition.
The polystyrenic resin composition shows excellent resistance to heat aging so that little change in physical properties or color is caused even after exposure to a high temperature for a long time, has excellent toughness, rigidity, heat resistance, and water resistance, and can advantageously be used as a material for various types of industrial product.
一种聚苯乙烯树脂组合物,包括(A)苯乙烯聚合物组合物,其中(a)1-99%(重量)具有对位构型的聚苯乙烯树脂,(b)1-99%(重量)聚酰胺树脂,(c)0.1%至 10%(重量百分比)的相容剂,该相容剂与组分(a)相容,并具有与组分(b)反应的极性基团,以及(d) 0%至 50%(重量百分比)的橡胶弹性体和/或改性橡胶弹性体,(B) 特定量的铜化合物和碘化合物、(C)酚类化合物,(D)N,N'-六亚甲基双(3,5-二叔丁基-4-羟基氢化肉桂酰胺),(E)硫代二丙酸酯或其衍生物,(F)铜抑制剂,(G)无机填料;以及用该聚苯乙烯树脂组合物制备的模塑制品。
该聚苯乙烯树脂组合物具有优异的耐热老化性,即使长时间暴露在高温下,其物理性质或颜色也几乎不会发生变化,并且具有优异的韧性、刚性、耐热性和耐水性,可用作各种工业产品的材料。
