Monomer compound comprising several cationic groups, process for making the same, and polymers comprising units deriving therefrom

摘要

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 R¹ is 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-C₆ linear 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, R⁵ and R⁶, which are identical or different, are hydrogen, alkyl, hydroxyalkyl, or aminoalkyl C₁-C₆ linear 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-C₁₂ polymethylene 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.
