The invention pertains to certain (per)fluoropolyether triazine derivatives comprising at least one triazine group and at least one fluoropolyoxyalkene chain (chain R) comprising a fluorocarbon segment having ether linkages in main chain, said chain Rcomprising at least one hydroxyl group, to a method for their manufacture and to their use in lubrication, in particular for lubricating sliding or moving parts of magnetic recording media. 1. A triazine derivative comprising at least one triazine group and at least one fluoropolyoxyalkene chain (chain R) comprising a fluorocarbon segment having ether linkages in main chain , said chain Rcomprises at least one hydroxyl group.2. The triazine derivative of claim 1 , wherein said fluoropolyoxyalkene chain (R) is a chain comprising repeating units R° claim 1 , said repeating units is selected from the group consisting of:{'br': None, '—CFXO—,\u2003\u2003(i)'}{'sub': '3', 'claim-text': {'br': None, '—CFXCFXO—,\u2003\u2003(ii)'}, 'wherein X is F or CF,'}{'sub': '3', 'claim-text': {'br': None, 'sub': 2', '2', '2, '—CFCFCWO—,\u2003\u2003(iii)'}, 'wherein X, equal to or different at each occurrence, is F or CF, with the provision that wherein at least one of X is —F,'} [{'br': None, 'sub': 2', '2', '2', '2, '—CFCFCFCFO—,\u2003\u2003(iv)'}, {'br': None, 'and'}, {'br': None, 'sub': 2', 'j, '—(CF)—CFZ—O—,\u2003\u2003(v)'}], 'wherein each of W, equal to or different from each other, are F, Cl, and H,'}{'sub': f', '3', 'f', '2', '2', '2', '2', '2', '2', '2', '2', '3', '3', '1', '3, 'wherein j is an integer from 0 to 3 and Z is a group of general formula —OR′T, wherein R′ is a fluoropolyoxyalkene chain comprising a number of repeating units from 0 to 10, said recurring units is selected from the group consisting of —CFXO—, —CFCFXO—, —CFCFCFO—, and —CFCFCFCFO—, with each of X being independently F or CF. and Tbeing a C-Cperfluoroalkyl group.'}4. The triazine derivative of claim 3 , wherein said at least one of Y claim 3 , Y′ claim 3 , ...
