摘要：

采用熔体共混的方法制备了三种增容剂增容的聚酰胺1010/聚丙烯（PA1010/PP）共混物，通过傅里叶变换红外光谱（FTIR）、力学性能和差示扫描量热（DSC）测试，对马来酸酐接枝乙烯-辛烯共聚物（POE-g-MAH）、马来酸酐接枝聚丙烯（PP-g-MAH）和乙烯-丙烯酸丁酯-甲基丙烯酸缩水甘油酯共聚物（PTW）对PA1010/PP共混物的增容作用进行了比较研究。结果表明，和非增容体系相比，PP-g-MAH、POE-g-MAH和PTW的拉伸强度分别是非增容体系的125 %、89 %和94 %，冲击强度分别是非增容体系的140 %、200 %和200 %，PTW具有较好的增容效果。

Abstract:

Three compatibilizers, maleic anhydride(MA)-grafted ethylene-octene copolymer (POE-g-MAH), MA-grafted polypropylene(PP-g-MAH), and ethylene-butylacrylate-glycidyl methacrylate terpolymer (PTW), were compared for their compatibilizing effects in the blends of polyamide 1010 and polypropylene (PA1010/PP). The compatibilized blends were characterized using Fourier transform infrared (FTIR), mechanical property testing, and differential scaning calorimetry (DSC). Compared with the plain PA1010/PP blends, the tensile strength of the compatibilized systems based on PP-g-MAH，POE-g-MAH，and PTW were 125 %, 89 %, and 94 %, and the impact strength of PP-g-MAH，POE-g-MAH，and PTW were 140 %, 200 %, and 200 % , respectively. One may conclude that the overall performance of PTW was the best.
