| 摘 要： | 本文研究了聚丙烯熔融接枝马来酸酐和不饱和羧酸混合单体对PP／PA6共混物的增容作用。研究结果表明，该接枝物是PP／PA6共混物的有效增容剂，能显著提高共混物的力学性能；接枝物的接枝率和用量影响增容共混物的力学性能；用接枝物增容后，PP／PA6表现更强的假塑性行为。溶融粘度增加，粘流活化能增加；随着接枝物用量的增加，共混物的MFI下降。

| Abstract: | The compatibization of a new melt graft copolymer of PP with MAH and unsaturated fatty aicd on PP／PA6 blend was studied．The results showed that the graft copolymer could improve the compatibility of PP／PA6 blend efficiently and the mechanical property was abviously increased and was a function of the amount of graft copolymer and percent grafting．The rheological measurement showed that compatibilized PP／PA6 blend possesed higher pseudoplasticity，melt viscosity and △Eη in comparision with simple PP／PA6 blend，and Melt Flow Index decreased with the increase of the amount of graft copolymer． |
