Novel fluorinated polymers by radical polyaddition: Inspiration and progress

摘要: The story of the outset and growth radical polyaddition bisperfluoroisopropenyl derivatives [CF2C(CF3)R C(CF3) CF2] with several organic compounds possessing carbon–hydrogen bonds is described. reaction afforded novel fluorinated polymers bearing such segments in polymer main chains as 1,4-dioxane, diethyl ether, dimethoxyethane, 18-crown-6, triethylamine, glutaraldehyde, alkanes which have never been supposed direct starting for preparation polymers. facile method hybrid alkylsilyl groups was developed diethoxydimethylsilane silsesquioxanes. Taking advantage high reactivity perfluoroisopropenyl group a acceptor, self-polyaddition cyclopolymerization were investigated. Triethysilyl ether [CF2 C(CF3)OSi(C2H5)3] proved to be most probable candidate self-polyaddition. Cyclopolymerization vinylacetate [CF2C(CF3) OCO CH2CH CH2] investigated afford five-membered-ring units chains. interconversion unstable carbon stable hydrocarbon had an important role reaction. addition presented herein may wide variety functional groups. © 2004 Wiley Periodicals, Inc.
