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.
