摘　　要：通过熔融挤出法制备了聚酰胺1010/氯化钙(PA1010/Ca Cl2)复合材料。研究了PA1010/Ca Cl2复合材料的熔融结晶行为。结果表明:PA1010存在双重熔融峰,分别代表完善程度不同的晶体;不完善晶体在较低结晶温度下生成且生成速率较慢,完善晶体则生成速率较快,不完善的晶体在熔融后可以重排为完善的晶体;Ca Cl2的加入可以促进不完善晶体的生成,并阻碍不完善晶体向完善晶体进行重排。Polyamide-1010 （PA1010）/CaCl2 composite was prepared via melt extrusion, and the melting behavior of the composite was studied by differential scanning caborimetry （DSC）. The results show that： multiple melting endotherms exist in PAt010 and these have been attributed to the presence of two kinds of crystal with different degrees of perfection. The imperfect crystal has a low crystallization rate and crystallization temperature, while the perfect crystal has a high crystallization rate, and the imperfect has a recrystallizing process at the heating scan. The addition of CaCl2 in PAl010 could prevent the generation of the perfect crystal and the recrystallizing of the imperfect of the imperfect crystal.
