Abstract

L'invention concerne des polymères échangeurs d'ions hydroxydes stables et des dispositifs comprenant ces polymères échangeurs d'ions hydroxydes stables. Lesdits polymères comprennent des ionènes, qui sont des polymères qui contiennent des amines ioniques dans leur squelette. Lesdits polymères sont solubles dans l'alcool et insolubles dans l'eau. Ces polymères présentent une absorption d'eau et une conductivité ionique qui sont corrélées à un degré de N-substitution. L'invention concerne également des procédés de formation desdits polymères et des membranes comprenant lesdits polymères. Ces polymères peuvent être utilisés par exemple comme ionomères dans des couches de catalyseurs destinées à des piles à combustible et à des électrolyseurs.
