Abstract
Abstract Improved retention on yarn and processing properties have been discovered in a composition of matter comprising meta and para pyromellitates <IMAGE> I. and <IMAGE> II. and 70 to 95 percent by weight of specific dimers and other oligomers of I. and II., wherein A is (CH2)2(CF2)nCF3, where n is 5 to 13 and B is CH2CHOHCH2Cl.
