Synthesis of highly branched perfluoroethers by direct fluorination, promising new materials based on the hexafluoroacetone–ethylene copolymer

Autor: E. T. Dumitru, G. E. Gerhardt, Richard J. Lagow

Publikováno v: Journal of Polymer Science: Polymer Chemistry Edition. 18:157-168

Direct fluorination of the hexafluoroacetone-ethylene copolymer, [CH2CH2OC(CF3)2]n, under conditions designed to promote fragmentation of the polymer chain has led to the synthesis of a number of structurally unusual branched perfluoropolyethers [CF2
