| 摘 要： | 以马来酸酐接枝ＰＰ（ＭＰＰ）作对照，研究了衣康酸接枝ＰＰ（ＩＰＰ）的熔体流动速率（ＭＦＲ）、接枝率（ＧＲ）妆枝配方的关系，ＰＡ６／接枝ＰＰ／ＰＰ合金的力学性能与接枝ＰＰ的特征参数、用量和合金组成比的关系。结果表明，ＩＰＰ对ＰＡ６／ＰＰ的增容效率明显高于ＭＰＰ，并具有显著提高材料冲击韧性的作用，可作为ＰＡ／ＰＰ高效增容剂兼增韧剂应用。

| Abstract: | By contrast with maleic anhydride grafted PP (MPP),relationships between melt flow rates(MFR) and grafting ratios (GR) of the itaconic acid grafted PP (g_PP)and its graft formula and relationships between mechanical properties of PA6/g_PP/PP alloy and feature parameter and doses of g_PP and ratios of PA6/(PP g-PP) are studied. Results show that the compatibilizing efficiency of IPP to PA6/PP is much higher than that of MPP and IPP can evidently enhance the impact toughness of the alloy,it can be used as the compatibilizer and impact modifier for PA/PP alloy. |
