ABSTRACT:
A polymer includes repetitive units derived from a monomer compound according to formula (I):wherein R1is a hydrogen atom, a methyl group or an ethyl group, A, which is identical or different, is a group comprising an ester group of formula -A1-C(O)—O-A2-, or an amide group of formula -A1-C(O)—NR10-A2-, wherein: R10, which is identical or different, is hydrogen or an alkyl, hydroxyalkyl, or aminoalkyl C1-C6linear or branched group, A1, which is identical or different is a covalent bond or a group of formula —(CH2)p1— wherein p1 is an integer of from 1 to 6, A2, which is identical or different, is a linear or branched hydrocarbon group comprising optionally N, O, or S heteroatoms or heterogroups, optionally substituted, optionally forming or comprising a cycle, R1, R2, R3, R5and R6, which are identical or different, are hydrogen, alkyl, hydroxyalkyl, or aminoalkyl C1-C6linear or branched groups, or, if inside the brackets, form a heterocycle with group A2, m is an integer of from 1 to 10, n is an integer of from 1 to 6, Z is —O—, —C(O)O—, or —C(O)NH—, B is a linear or branched C2-C12polymethylene chain, optionally comprising heteroatoms or heterogroups, and optionally substituted with one or several hydroxy or amino groups, and X−, which are identical or different, are counter ions.
