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 are provided. The invention also relates to a process for making these monomer compounds. The process is highly selective and prevents unwanted reactions leading to undesired structures. The invention relates also to polymers, including copolymers, comprising units deriving from said monomer compounds. The monomer compounds comprise several cationic groups, e.g. those having the following 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 -A-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, preferably 1, -A², which is identical or different, is a linear or branched hydrocabron group comprising optionally N, O, or S hereroatomes or heterogroups, optionally substituted, optionally forming or comprising a cycle, such as a heterocycle, A² preferably being a group of formula -(CH₂)_p2- wherein p² is an integer of from 1 to 6, - R¹, R², R³, 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, preferably of from 1 to 2, - n is an integer of from 1 to 6, preferably 2 or 4, Z is -O-, -C(O)O, or -C(O)NH-, B is linear or branched C₂-C₁₂ polymethylene chain, preferably a C₃-C₆ one, optionally comprising heteroatoms or heterogroups, such as O or NH, and optionally substituted with one or several hydroxy or amino groups, and -X^-, which are identical or different, are counter ions.
