PERFLUOROALKYL-SUBSTITUTED ESTERS OF PYROMELLITIC ACID

摘要

Perfluoroalkyl-alkyl-sulfide or sulfonyl-alkylene esters of meta- and para-pyromellitates, partially esterified with 3-chloro-1,2-propane diol, of the formulae: I or II or mixtures thereof, wherein Rf is perfluoroalkyl of 3 to 18 carbon atoms, and m is 0 or 2, are useful for incorporation into organic polymers to render them oil repellent and soil resistant.
