摘　　要：研究了ＰＰ－ｇ－ＧＭＡ对ＰＰ／ＰＡ６（羧端基尼龙）共混物的反应增容作用及其对共混物力学性能的影响，考察了反应增容与非反应增容的优劣．研究结果表明，ＰＰ－ｇ－ＧＭＡ对ＰＰ／ＰＡ６共混物具有显著的反应增容作用，并且增容效果优于ＰＰ－ｇ－ＭＡＨ的非反应增容效果；ＰＰ－ｇ－ＧＭＡ的反应增容对共混物力学性能的影响远大于ＰＰ－ｇ－ＭＡＨ的非反应增容对共混物力学性能的影响．The effects of reactive compatibilizer PP-g-GMA(glucidyl methylacrylate grafted PP) and non-reactive compatibilizer PP-g-MAH(maleic anhydride grafted PP) on the morphology and mechanical properties of polypropylene/polyamide 6(with carboxylic end group) blends are investigated in this paper.The results have indicated that:(1) PP-g-GMA is more efficient than PP-g-MAH in compatibilizing the PP/PA6 blends;(2) the reactive compatibilizer has much more effects on mechanical properties than the non-reactive compatibilizer.
