    • Reinforced resin compositions exhibiting excellent heat resistance and appearance, and containing by weight: (a) at least 30% of a polyethylene terephthalate-type resin, (b) 5 to 60% glass fiber, (c) 0.03 to 5% of one or more salts of organic carboxylic acids with metals of the Groups Ia and IIa of the Periodic Table, and (d) 0.1 to 20% of a sorbitan derivative are disclosed. Optionally liquid or solid paraffin or polyethylene wax is incorporated in an amount of 0.3 to 5% based on the total composition may be incorporated if a white article is desired.Molded articles prepared from these compositions, high in heat resistance and uniform appearance, even if the thickness of the molded article is small or uneven or the molding operation is carried out at a relatively low mold temperature, are also disclosed. Molding temperature dependence and thickness dependence on the heat distortion temperature of the molded article are remarkably improved as well.
    • 表现出优异的耐热性和外观的增强树脂组合物,其重量含量:(a)至少30%的聚对苯二甲酸乙二醇酯类树脂,(b)5至60%的玻璃纤维,(c)0.03至5%的一种或 公开了更多的有机羧酸盐与周期表的Ia和IIa族的金属,和(d)0.1-20%的脱水山梨醇衍生物。 任选地,如果需要白色制品,则可以加入基于总组合物的0.3至5%的液体或固体石蜡或聚乙烯蜡。 即使模制品的厚度小或不均匀,或者在相对较低的模具温度下进行模塑操作,也公开了由这些组合物制备的模制品,耐热性和均匀的外观。 模塑制品的热变形温度依赖性和厚度依赖性也显着提高。
