Poly[bis(3-methylphenoxy) phosphazene] was sulfonated in a solution with SO 3 and solution-cast into 100 -200-m-thick membranes from N,N-dimethylacetamide. The degree of polymer sulfonation was easily controlled and water-insoluble membranes were fabricated with an ion-exchange capacity (IEC) as hi
