Poly(2,6-dimethyl-1,4 -phenylene oxide) (PPO) is a chemically resistant polymer and, therefore, an attractive material for the formation of membranes. However, membranes of unmodified PPO prepared by an immersion precipitation possess very low hydraulic permeabilities at the filtration processes. T
## Abstract A series of anion exchange membranes with pyridinium groups were prepared by aminating 100% bromomethylated poly(2,6βdimethylβ1,4βphenylene oxide) with 4βvinylpyridine. These membranes exhibited higher ion exchange capacity, lower water uptake, lower area resistance, and better thermal
