Abstract

The copolymer is of formula (I): (where R1 is tetravalent org. gp., each R2 is a trivalent org. gp., each Ar is a divalent org. with x SO3H gps., x is 1-4, each Ar' is a divalent org. gp., n and n' = positive integers and m and m' = positive integers or 0). The copolymer can produce liqs. of high resistivity.
