摘要
研究了液晶共聚酯酰胺LC30对聚对苯二甲酸乙二酯/聚酰胺66(PET/PA66)共混物的原位增容、增强、增韧作用。结果表明,LC30有效地改善了PET/PA66共混物的形态结构,对PET/PA66共混物起到了明显的增容作用。加入LC30,能使PET/PA66共混物的拉伸强度、冲击性能显著提高,当LC30为2.5～5份时,效果尤佳。
This paper studied the functions of liquid crystalline copolyesteramide (LC30) in compatibilizing, reinforcing and toughening in situ the blends of poly(ethylene terephthalate) (PET) and polyamide 66 (PA66) . The results showed that LC30 acted as compatibilizer and effectively improved the morphology and microstructure of PET/PA66 blends. The tensile strength and impact property of the blends was remarkably raised with introduction of LC30. The blends showed excellent tensile and impact strength when the dosage of LC30 was 2.5 - 5 parts.
