    • A polyetheresteramide having good heat resistance, permanent antistatic property and superior compatibility with thermoplastic resins and a resin composition containing of the polyetheresteramide are disclosed, wherein the polyetherester-amide consists essentially of a polyamide oligomer with carboxylic chain ends having a number average molecular weight between 200 and 5,000 and a bisphenol compound with oxyalkylene units having a number average molecular weight between 300 and 3,000. Antistatic resin compositions with good antistatic property and heat resistance are obtained from compositions comprising 3 to 40% by weight of the polyetheresteramide and 60 to 97% by weight of thermoplastic resins. The antistatic resin compositions can contain as compatibilizers vinyl polymers having functional groups such as carboxyl and epoxy groups or block polymers containing polyolefin blocks and aromatic vinyl polymer blocks. To further improve the antistatic property of the resin composition a composition comprising at least 97% by weight of the polyetheresteramide and at least 0.01% by weight of an alkali metal or alkaline earth metal halide can be used in the same way as the polyetheresteramide.
    • 公开了具有良好的耐热性,永久抗静电性和与热塑性树脂的相容性优异的聚醚酯酰胺和含有聚醚酯酰胺的树脂组合物,其中聚醚酯 - 酰胺基本上由具有数均分子量为200 和5,000以及数均分子量在300和3,000之间的具有氧化烯单元的双酚化合物。 具有良好抗静电性和耐热性的抗静电树脂组合物由包含3至40重量%的聚醚酯酰胺和60至97重量%的热塑性树脂的组合物获得。 抗静电树脂组合物可以含有作为相容剂的具有官能团的羧基和环氧基的乙烯基聚合物或含有聚烯烃嵌段和芳族乙烯基聚合物嵌段的嵌段聚合物。 为了进一步提高树脂组合物的抗静电性,可以以与聚醚酯酰胺相同的方式使用包含至少97重量%的聚醚酯酰胺和至少0.01重量%的碱金属或碱土金属卤化物的组合物。
