## Abstract A series of anion exchange membranes with pyridinium groups were prepared by aminating 100% bromomethylated poly(2,6‐dimethyl‐1,4‐phenylene oxide) with 4‐vinylpyridine. These membranes exhibited higher ion exchange capacity, lower water uptake, lower area resistance, and better thermal
Positively charged membrane with various charged groups were prepared by in situ amination and phase inversion in which the amine-organic solution and bromomethylated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO) was cast and immerged into an ethanol coagulation bath. The separation performance and
