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

Claim (Index 10):
The polymer (P) according to  claim 7 , said polymer (P N *) complying with the following formula (P-I):\n T-(R pf )\u2014(B*)\u2014(*C*)\u2014(B*)\u2014(R pf )\u2014(B*)\u2014(C*) \u2003\u2003(P-I) wherein\n \u2014(R pf ) is a chain of formula \u2014(CFX) a O(R f )(CFX\u2032) b \u2014; \n wherein\n a and b, equal or different from each other, are equal to or higher than 1; \n 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; \n (R f ) comprises repeating units R 602  , said repeating units being independently selected from the group consisting of:\n (i) \u2014CFXO\u2014, wherein X is F or CF 3 ; \n (ii) \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 \u2014F; \n (iii)\u2014CF 2 CF 2 CW 2 O\u2014, wherein each of W, equal or different from each other, are F, Cl, H; \n (iv)\u2014CF 2 CF 2 CF 2 CF 2 O\u2014; and \n (v) \u2014(CF 2 ) j \u2014CFZ\u2014O\u2014 wherein j is an integer from 0 to 3 and Z is a group of general formula \u2014)\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 \n \n \u2014(B*) is a divalent alkyl chain comprising from 1 to 20 carbon atoms, said alkyl chain being optionally interrupted by at least one oxygen atom and/or optionally substituted with at least one hydroxy group and/or with a perfluoroalkyl group comprising from 1 to 3 carbon atoms; \u2014(*C*) is a linear or branched alkyl chain comprising from 1 to 10 carbon atoms, and being optionally interrupted by at least one heteroatom selected from N, O and S and/or by a 5- to 10-membered aromatic moiety optionally comprising one or more heteroatoms and optionally substituted with a linear or branched alkyl chain comprising from 1 to 6 carbon atoms, said aromatic moiety and/or said alkyl chain being optionally substituted with at least one hydroxy group; (C*) is a linear or branched alkyl chain comprising from 1 to 20 carbon atoms, said alkyl chain being optionally interrupted by one or more heteroatoms and being optionally substituted with a 5- to 10-membered aromatic moiety, or a 5- to 10-membered aromatic moiety optionally substituted with a linear or branched alkyl chain comprising from 1 to 6 carbon atoms, wherein said alkyl chain or said a 5- to 10-membered aromatic moiety further comprising at least one hydroxy group and at least one amino group; And T is selected from the group comprising \u2014H, \u2014F, \u2014Cl, a straight or branched perfluoroalkyl group comprising from 1 to 3 carbon atoms, and chain \u2014(B*)\u2014(C*).
