Abstract:
A composition comprising one or more additives of formula:R.sub.f --CFX--Lin which R.sub.f is --(C.sub.3 F.sub.6 O).sub.m' (CFXO).sub.n' -wherein the unit (C.sub.3 F.sub.6 O) and (CFXO) are perfluorooxyalkylenic units statistically distributed along the chain; .sub.m' and .sub.n' are integers such as to give products with boiling points from about 25.degree. to 300.degree. C., and the ratio .sub.m'/n' is from 5 to 40, X is equal to F or CF.sub.3 ; L is a moiety containing polar groups selected from the group consisting of --CH.sub.2 OH; CH.sub.2 OCH.sub.2 CH.sub.2 OH; CH.sub.2 (OCH.sub.2 CH.sub.2).sub.n' ""OR' wherein .sub.n' "" is an integer between 2 and 15 and R' is H, CH.sub.3 and COCH.sub.3 ; and CONHCH.sub.2 CH.sub.2 OH.
