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

Claim (Index 1):
A polymer [polymer (P)] comprising:\n at least one (per)fluoropolyether chain (R pf ) and at least one chain (C) comprising at least one hydroxy group and at least one group (H) comprising a heteroatom selected from the elements belonging to group 15 of the periodic table, provided that polymer (P) does not comprise amide group(s) and is different from a polymer of formula\n R 1 RN\u2014[CH 2 ] r \u2014[CF 2 O] s \u2014[CF 2 CF 2 O] t \u2014[CF 2 O] u \u2014CF 2 \u2014[CH 2 ] v \u2014NRR 1  \n wherein r, s, t, u and v are independently zero or an integer, with the proviso that s, t and u are not all zero, and R and R 1  are independently selected from \u2014[OCH 2 CH 2 ] y OH, \u2014OCH 2 CH(OH)CH 2 OH, \u2014CH 2 CH 2 OH and \u2014CH 2 CH 2 CH 3 .
