Claims17
A polymer [polymer (PA)] comprising:
- less than 50 mol. % relative to the total number of moles of recurring units in polymer (PA) of recurring units comprising a piperidine ring and complying with formula [RINP]:
- at least one recurring unit [RPA] selected from:
- [RPA(I)]—[RPA(II)][HN-GI-NH]—[(O═)C-GII-C(═O)]
- [RPA(III)][HN-GIII-C(═O)]
- wherein:
- each of GI, GII and GIII is an optionally substituted linear or branched alkyl chain comprising from 1 to 16 carbon atoms, an optionally substituted cycloalkyl group comprising 6 carbon atoms, or an optionally substituted phenylene;
- wherein said recurring units [RINP] and [RPA] are randomly disposed along the backbone of said polymer (PA) and the sum of the number of moles of recurring units [RINP] and [RPA] is 100%.
