Abstract of the Disclosure This invention relates to new perfluoroalkyl substituted esters, diesters and polyesters which contain at least one cyclic 5-membered anhydride group or two carboxy groups, as well as half amides and half esters thereof; further to the synthesis of these compounds and to their use as surface-active reactants in polycondensate resin systems. The anhydrides are synthesized by reaction of perfluoroalkyl substituted alcohols or diols with di- anhydrides or an anhydride-acid chloride and correspond to the general formula Image wherein Q is the tetra-radical rest of a tri- or tetra- carboxylic acid, which contains at least one 1,2-dicarboxy grouping, X is hydrogen or COOH, Rf is a perfluoroalkyl or perfluoroalkoxy- perfluoroalkyl group of 4 to 18 carbon atoms, a is 1 or 2, A is hydrogen or the group of the formula Image wherein m is an integer from 0 to 5, and R3 is the residue of a Rf substituted alcohol containing olefinic double bonds or oxygen, sulfur and/or nitrogen atoms or R3 is the residue of a Rf substituted diol.
