CA 2745367

The invention relates to a method for producing polymeric, ionic imidazolium compounds, characterized in that - an .alpha.-dicarbonyl compound, - an aldehyde, - at least one amino compound having at least two primary amino groups, - optionally an amino compound having only one primary amino group, and - a hydracid are reacted with each other, wherein optionally the carbonyl groups of the .alpha.-dicarbonyl compound and of the aldehyde can be present also as hemiacetals, acetals, hemiketals, or ketals.

L'invention concerne un procédé de fabrication de composés imidazolium ioniques polymères, qui consiste à faire réagir les uns avec les autres un composé alpha-dicarbonyle, - un aldéhyde, - au moins un composé amino présentant au moins deux groupes amino primaires, - éventuellement un composé amino ne présentant qu'un groupe amino primaire et un hydracide, les groupes carbonyle du composé alpha-dicarbonyle et de l'aldéhyde pouvant également être éventuellement présents sous la forme d'un hémiacétal, d'un acétal ou d'un hémicétal, ou d'un cétal.
