Abstract
To address the problem of insufficient biodegradability of perfluorinated surfactants, the present invention provides biodegradable fluorosurfactants derived from olefins having —CHR, —CHRf, —CHF, and/or —CHgroups, where R is an alkyl group and Rf is a perfluoro or fluroroalkyl group. Preferably, the —CHR, —CHRf, —CHF, and/or —CHgroups are contained within partially fluorinated alkenes.
