摘要
综述了超临界CO2(SC-CO2)协助聚烯烃后功能化接枝改性过程中的溶胀条件和渗透机理。SC-CO2协助固相接枝技术能明显改善接枝产物的均匀性,使后处理工艺简单,是很有发展前景的聚烯烃功能化改性的方法。
The influence of swelling condition and permeation mechanism on the grafting reaction in the supercritical CO2 assisted polyolefin post-functionalzation grafting modification process has been reviewed.SC-CO2-assisted solid phase grafting copolymerization technology can improve the uniformity of grafted products significantly,make the post-processing simple,and has a great development prospect in polyolefin functionalization grafting modification.
