聚丙烯化学改性方法

The Way of Chemical Modification of Polypropylene

综述了聚丙烯的化学改性方法,包括接枝、交联、共聚等,接枝主要包括熔融接枝、溶液接枝、悬浮接枝、辐射接枝、超临界CO_2协助接枝、固相接枝及非极性单体在PP上的接枝,交联改性主要包括有机氧化物交联、氮化物交联、辐射交联及等离子体交联,最后简要介绍了共聚改性以及PP改性的最新进展。

The chemical modification of polypropylene was introduced,including grafting,crosslinking,copolymerization and so on.The melt grafting,solution grafting, suspention grafting,radiation grafting,solid state grafting with assistance of SC CO_2 and non-polar monomer grafting onto PP were included in grafting copolymerization.The crosslinked organic oxides,nitrieds,radiation and plasma were included in crosslinking modification. In the end,the copolymerization and the latest develoling on modification of PP are briefly descripted.
