Abstract
Oligomers containing pyromellitic rings, divalent linking groups, pendant fluoroalkoxy or hydrocarbon alkoxy groups and pendant polar groups of various kinds impart soil repellency to fibers that persists after repeated laundering. An exemplary material is prepared by the reaction of pyromellitic difluoroester/diacid chloride with 1,4-butanediol (the linking group) and 3-chloro-1,2-propanediol (the pendant polar group).
