Process for the preparation of perfluoropolyoxyalkylenes with hydroxyl end groups

Curable fluoroelastomer compositions

Fluoropolyethers having functional groups, consisting of randomly distributed sequences of perfluoropolyoxyalkylene units selected from: ##STR1## where X is F or CF.sub.3 T, T', T'=a perfluoroalkyl group containing from 1 to 3 carbon atoms and one or two atoms of Cl, Br or I;

Functionalized fluoropolyethers

Method for the water removal from a surface, which comprises covering the surface with a composition having specific weight higher than that of the water, and subsequently removing water from the composition by skimming, such composition comprising a (per)fluoropolyether having molecular weight comprised between 300 and 1500 and a non ionic additive having a (perfluoropolyethereal structure similar to that of the solvent, linked to an hydrogenated part of hydrophilic type, the molecular weight of the (per)fluorinated part is comprised between 400 and 1200 and the ratio by weight between (per)fluorinated part and hydrogenated part is comprised between 1.5 and 3.5.

Composition for the removal of water from a surface

Use of additives of the classes of mono- and/or di-hydroxypolyfluoroethers comprising the fluoropolyoxyalkylenic repeating units chosen from the following ones: (C.sub.3 F.sub.6 O); (CFXO) wherein X=F, CF.sub.3 ; (CH.sub.2 CF.sub.2 CF.sub.2 O); (CF.sub.2 (CF.sub.2).sub.z CF.sub.2 O) wherein z is an integer equal to 1 or 2; (C.sub.2 F.sub.4 O), in curable compositions of fluoroelastomers to improve the coefficient of friction without lowering the adhesion with bonding agents to metal reinforcements.
