Abstract:
The present invention relates to novel (per)fluoropolyether polymers and their use as lubricants, in particular for Magnetic Recording Media (MRM).

Claim (Index 6):
The polymer (P) according to  claim 1 , which is polymer (P N ) comprising:\n one (per)fluoropolyether chain [chain (R pf )] and at least one chain [chain (C)] comprising at least one hydroxy group and at least one amino group, wherein said chain (R pf ) is a chain of formula \u2014(CFX) a O(R f )(CFX) b \u2014, wherein a and b, equal or different from each other, are equal to or higher than 1; X and X\u2032, equal or different from each other, are \u2014F or \u2014CF 3 , provided that when a and/or b are higher than 1, X and X\u2032 are \u2014F; and (R f ) comprises, preferably consists of, repeating units R \u2218 , said repeating units being independently selected from the group consisting of:\n (i-a) \u2014CF(CF 3 )O\u2014; \n (ii-a) \u2014CFXCFXO\u2014, wherein X, equal or different at each occurrence, is F or CF 3 , with the proviso that at least one of X is \u2014CF 3 ; \n (iii-a) \u2014CF 2 CF 2 CF 2 O\u2014; \n (iv-a) \u2014CF 2 CF 2 CF 2 CF 2 O\u2014; \n (v-a) \u2014(CF 2 ) j \u2014CFZ\u2014O\u2014 wherein j is an integer from 0 to 3 and Z is a group of general formula \u2014O\u2014R (f-a) -T, wherein R (f-a)  is a fluoropolyoxyalkene chain comprising a number of repeating units from 0 to 10, said recurring units being selected from: \u2014CFXO\u2014, \u2014CF 2 CFXO\u2014, \u2014CF 2 CF 2 CF 2 O\u2014, \u2014CF 2 CF 2 CF 2 CF 2 O\u2014, with each of each of X being independently F or CF 3  and T being a C 1 -C 3  perfluoroalkyl group.
