ABSTRACT:
This invention describes 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; their synthesis and their use as surface-active reactants in polycondensate resin systems.
The anhydrides are synthesized by reaction of perfluoroalkyl substituted alcohols or diols with dianhydrides or an anhydrides-acid chloride and have the general structure ##STR1## wherein: Q is the tetra-radical rest of a tri- or tetracarboxylic acid, which contains at least one 1,2-dicarboxy grouping,
