Reinforced polyethylene terephthalate molding resin compositions with glossy surface are provided which crystallize rapidly after being injection molded and which have engineering resin performance characteristics. In addition to polyethylene terephthalate and glass fibers, the compositions contain an aliphatic polyester, an ionic hydrocarbon polymer, an antioxidant, and a secondary amide. Optionally, the compositions may contain a portion of glass flakes, mica or other filler. The compounds can be flame retarded with a brominated polystyrene and an antimonate without substantial change in properties.
本发明提供了表面光亮的增强聚对苯二甲酸乙二醇酯模塑树脂组合物,这种组合物在注塑成型后可迅速结晶,并具有工程树脂的性能特点。除了聚对苯二甲酸乙二醇酯和玻璃纤维外,组合物还含有脂肪族聚酯、离子烃聚合物、抗氧化剂和仲酰胺。也可选择在组合物中加入部分玻璃片、云母或其他填料。这些化合物可以用溴化聚苯乙烯和锑酸盐进行阻燃处理,而不会在性质上发生重大变化。
