    Abstract: A method of manufacturing cyclophosphazenes PFPE derivatives to be used in the lubrication of magnetic recording media is herein provided. The method comprises: a) a (per)fluoropolyether (PFPE) polyol [PFPE (P pol )] comprising a fluoropolyoxyalkylene chain (R f ) having two chain ends, each chain end comprising at least one hydroxy group, and b) the corresponding alkoxide of perfluoropolyether (P pol ) [PFPE (P alk )] wherein the equivalent concentration of PFPE (P alk ) in PFPE (P pol ) is lower than 30%, preferably ranging from 5% to 15%; 2) contacting mixture (M) with a perhalocyclophosphazene (CP halo ) to provide a mixture (M1) containing an equivalent ratio of PFPE (P alk )/(CP halo ) of at least 1; 3) allowing mixture (M1) to react until complete disappearance of P-Cl groups to provide a mixture (M2); 4) submitting mixture (M2) to hydrolysis to provide a mixture (M3); 5) optionally removing (P pol ) from mixture (M3) to provide a mixture (M4). A method of purifying mixture (M4) is also herein provided.

    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 R f ) 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 R a ), 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 -CH 2 CH 2 O- and -CH 2 CH(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 -CH 2 CH 2 O- units, chain Rf does not consist only of -CF 2 CF 2 O-units. Lubricant compositions containing the polymer and methods for preparing the polymer are also herein disclosed.
