摘要
Fluorinated telomers which can be defined by the formula: RF-CmH2m-(CH2-CR1R2)nX (I) wherein RF is a poly- or perfluorinated radical; X is iodine, chlorine or bromine; m is 0, 1 or 2; n is from 5 to 1000; R1 is hydrogen or methyl; and R2 is a -COOH or -CONR3R4 group, R3 and R4 being hydrogen or alkyl or hydroxyalkyl radicals, such telomers being obtained by free radical reaction of an ethylenic monomer CH2=CR1R2 with a fluorinated telogen RF-CmH2m-X, and being excellent surfactants in aqueous media with special usefulness as additives to fire-fighting protein-based emulsifiers.
