摘要
阐述了聚丙烯(PP)接枝改性方法及其研究进展。对溶液法接枝、熔融法接枝、辐射法接枝等工艺技术进行了探讨,同时对各种不同接枝方法的特点进行了比较,得出超临界CO2协助固相接枝工艺是相对环保、实用的聚丙烯接枝改性方法的结论。
The paper expounded a few methods for polypropylene (PP) grafting modification and their research progresses.It discussed the technologies including those of solution grafting, melt grafting,radiation grafting and supercritical CO2 assisted solid-phase grafting.The characteristics of each method were discussed as well.It is concluded that the supercritical CO2 assisted solid-phase grafting technology is the relatively practical and green method.
