Fluorinated imides useful for imparting repellency of low surface tension fluids to thermoplastic polymers of formulae ##STR1## wherein R.sub.1 is F(CF.sub.2).sub.x --(CH.sub.2).sub.m, or F(CF.sub.2).sub.x SO.sub.2 N(R.sub.5) (CH.sub.2) .sub.p wherein x is from about 4 to about 20, m is from about 2 to about 6, p is from 1 to about 12, and R.sub.5 is an alkyl radical of from 1 to about 4 carbons; R.sub.2 is a linear, branched or cyclic alkylene or poly(oxyalkylene) hydrocarbon group having from about 2 to about 15 carbons; R.sub.3 is selected from the group consisting of F(CF.sub.2).sub.x --(CH.sub.2).sub.m, F(CF.sub.2).sub.x --(CH.sub.2).sub.m --OC(O)--(CH.sub.2).sub.n, and F(CF.sub.2).sub.x SO.sub.2 N(R.sub.5)(CH.sub.2).sub.p OC(O)(CH.sub.2).sub.n wherein x is from about 4 to about 20, m is from about 2 to about 6, n is about 2 to about 12, p is from 1 to about 12, and R.sub.5 is an alkyl radical of from 1 to about 4 carbons; R.sub.4 is an alkyl or alkenyl group of from about 4 to about 20 carbons, and R.sub.6 is a linear or branched alkyl having from about 4 to about 20 carbons.
A compound of formula A ##STR11## wherein R.sub.1 is F(CF.sub.2).sub.x --(CH.sub.2).sub.m or F(CF.sub.2).sub.x SO.sub.2 N(R.sub.5) (CH.sub.2).sub.p wherein x is from about 4 to about 20, m is from about 2 to about 6, p is from 1 to about 12, and R.sub.5 is an alkyl radical of from 1 to about 4 carbons and
