Abstract: A lubrication method comprising applying to a surface to be lubricated a polymer comprising a partially or fully fluorinated, straight or branched, polyoxyalkylene chain (chain Rf) having two chain ends, wherein one or both chain end(s) bear(s) a hydroxy- or alkoxy-terminated polyoxyalkylene chain free from fluorine atoms (chain 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(J)O—, wherein J is independently straight or branched alkyl or aryl, with the proviso that, if both chain ends bear a hydroxy-terminated chain Ra comprising only —CH2CH2O— units, chain Rf does not consist only of —CF2CF2O-units. Lubricant compositions containing the polymer and methods for preparing the polymer are also herein disclosed.

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: The present invention relates to a novel process for the synthesis of (per)fluoropolyether polymers, to certain novel (per)fluoropolyether polymers. The present invention also relates to the use of the (per)fluoropolyether polymers thus obtained as intermediate compounds for the manufacture of further polymers suitable for use as lubricants, notably for magnetic recording media (MRM).
