ABSTRACT:
Fluorinated esters based on multi-ring anhydride systems are disclosed which have excellent anti-soiling properties, durability and resistance to laundering. The compounds are represented by the formula ##STR1## wherein n is 2 or 3, Q is a linking group such as --CO--, --O--, or (C.sub.a H.sub.2a+2-n --(O.sub.2 C).sub.n, R.sub.f is a fluorinated radical, and R is derived from an epoxide such as ethylene oxide or epichlorohydrin. Also disclosed are polyester and nylon fibers having these compounds incorporated therein, and a process for producing such soil-repellent fibers.
