ABSTRACT:
Monomer compounds comprising several cationic groups, a process for making such compounds and polymers derived from such compounds are provided. The monomer compounds are 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, R4, 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.
