Abstract
Perfluoroalkyl-alkyl-sulfide or sulfonyl-alkylene esters of meta- and para-pyromellitates, partially esterified with 3-chloro-1,2-propane diol, of the formulae: ##STR1## or mixtures thereof, wherein R.sub.f is perfluoroalkyl of 3 to 18 carbon atoms, and PA1 m is 0 or 2, are useful for incorporation into organic polymers to render them oil repellent and soil resistant.
