Patent

CA 2407250

The present invention relates to ionically and covalently cross-linked polymers and polymer membranes having recurrent units of the general formula (1), wherein Q is a link, oxygen, sulfur, (2) or (3) and the R radical is a divalent radical of an aromatic or heteroaromatic compound, and which are characterized in that a) R radical comprises at least partially substituents of general formula (4A), (4B), (4C), (4D), (4E), (4F), (4G) and/or (4H), b) R radical comprises at least partially substituents of the general formula (5A) and/or (5B) and/or the R radical is at least partially a group of the general formula (5C) and/or (5D) and c) the R radical comprises at least partially bridges of the general formula (6) linking at least to R radicals together, R1, R2, R3, R4, R5, M, X, Y, Z and m having the herein-mentioned meanings.

La présente invention concerne des polymères et des membranes polymères réticulés par voie ionique et par covalence, qui présentent des unités récurrentes de formule générale (1), dans laquelle Q représente une liaison, oxygène, soufre, (2) ou (3) et le radical R représente un radical bivalent d'un composé aromatique ou hétéroaromatique, et qui sont caractérisés en ce que a) le radical R présente au moins partiellement des substituants de formule générale (4A), (4B), (4C),(4D), (4E), (4F), (4G) et/ou (4H), b) le radical R présente au moins partiellement des substituants de formule générale (5A) et/ou (5B) et/ou le radical R est au moins partiellement un groupe de formule générale (5C) et/ou (5D) et c) le radical R présente au moins partiellement des ponts de formule générale (6), qui lient au moins deux radicaux R ensemble, R<1>, R<2>, R<3>, R<4>, R<5>, M, X, Y, Z et m ayant les significations énoncées dans la description de cette invention.
