摘要
以马来酸酐(MAH)、苯乙烯(St)多单体熔融接枝聚丙烯(PP)[PP-g-(MAH-co-St)]为增容剂改性聚酰胺(PA)6/PP体系,制备了PA6/PP合金,研究了合金的流变性能。结果表明,PP-g-(MAH-co-St)增容的PA 6/PP共混物熔体属假塑性流体,熔体黏度随PP-g-(MAH-co-St)含量的增加逐渐增大。在较低剪切速率(99,90s^(-1))下,体系分散相PP的粒径尺寸较小;剪切速率从99.90s^(-1)到706.50s^(-1),分散相粒径增加;剪切速率从706.50s^(-1)增到5 002.65 s^(-1),分散相粒径又相对减小。
A kind of alloy of polyamide 6 and polypropylene （PA 6/PP） was prepared via PP system with the maleic anhydride （MAH） and styrene-based multi-monomers melt modification of the PA 6/ grafted PP [PP-g-（MAH- co-St）] as compatibilizer. The study on rheological property indicates that the PA 6/PP system compatibilized with PP-g-（MAH-co-St） can be classified as pseudoplastic fluid, its melt viscosity increases gradually with the content of PP-g-（MAH-co-St）. As the dispersed phase, PP exists in the form of particles with smaller size at lower shear rate （99.90 s^-1） and its particle diameters augment when the shear rate rises to 706.50 s^-1 from 99.90 s^-1. However, the particle diameters tend to decline if the shear rate continues to rise from 706.50 s^-1 to 5 002.65 s^-1.
