Abstract: This invention provides for a composition particularly useful in a method comprising applying the composition to a surface to be lubricated, said composition comprising: at least one polymer (P) comprising a partially or fully fluorinated, straight or branched, polyoxyalkylene chain (Rf) having two chain ends, wherein one or both chain end(s) bear(s) a hydroxy-, alkoxy- or acyl-oxy-terminated polyoxyalkylene chain free from fluorine atoms (Ra), said chain comprising from 4 to 50 fluorine-free oxyalkylene units, said units being the same or different from one another and being selected from —CH2CH2O— and —CH2CH(O)O—, wherein J is independently straight or branched alkyl or aryl, preferably methyl, ethyl or phenyl and water.

Abstract: A convenient process for the manufacture of alkoxylated derivatives of PFPE alcohols is herein provided. The process envisages the use of a boron-based catalyst and an iodine source and is characterised in that a PFPE alkoxide is prepared separately, contacted with a boric acid triester of the same PFPE alcohol and finally submitted to alkoxylation in the presence of an iodine source. The process allows achieving an alkoxylation degree of at least 2 with high yields and under conditions that are convenient on an industrial scale.
