含硅功能化聚烯烃:合成及应用

聚烯烃功能化改性是获得高性价比新材料的有效途径。含硅功能化聚烯烃(SFPO)是聚烯烃分子结构中含有机硅功能基团或有机硅聚合物链段的一类功能化聚烯烃的统称。由于有机硅功能基团及有机硅聚合物特殊的理化性质,SFPO通常具有丰富反应性或优异性能,成为一类有代表性的功能化聚烯烃。SFPO可以作为反应性中间体,用于制备具有复杂拓扑结构的功能化聚烯烃(如星型聚合物、梳型聚合物、接枝共聚物)或聚烯烃共价键接枝改性纳米材料;SFPO还可作为功能性添加剂(如增容剂、加工助剂,表面改性剂),用于开发聚烯烃新材料。近年来,研究人员在含硅功能化聚烯烃研究领域取得了系列进展,本文旨在对相关工作进行系统总结,以期引起同行注意并促进相关研究深入发展。

Silicon-Containing Functionalized Polyolefin:Synthesis and Application

Functionalization of polyolefin is an efficient route to new polymer materials with high performance/price ratio.Silicon-containing functional polyolefin(SFPO)is a kind of functional polyolefin that incorporate functional silicone groups or polysiloxane segments in the structure of polyolefin.Due to special physiochemical properties of silicone groups or polysiloxane,SFPO often possesses reactivity or advanced properties and forms a new group of functional polyolefin.SFPO can function as reactive intermediates in synthesizing functional polyolefins with complex topologies(star polymer,brush polymer and graft copolymer)or preparing polyolefin covalently grafted nanomaterials.SFPO can also serve as functional additives(compatibilizer,polymer process aid and surface modifier)in developing new polyolefin materials.In recent years,researchers have obtained a series of fruitful results on the syntheses and applications of SFPO.This review aims to cover the recent progress on SFPO,which we hope may arouse the attention of related researchers and promote further achievements in related research areas.
