Synthesis and surfactant properties of fluoroalkylated oligomers containing carboxy groups

Abstract
The reactions of acrylic acid with various of difluoroalkanoyl peroxides {(RfCO2)2, Rf= C3F7, C6F13 CF(CF3)[OCF2CF(CF3)]mOC3F7, m= 0, 1, 2} have been found to give new fluoroalkylated oligomers containing carboxy groups {Rf[CH2CH(CO2H]nRf} under mild conditions, and these compounds are able to reduce the surface tension of water to 10 mN m–1 levels.
