Abstract

See full text

Sulfonyl-containing polymeric materials are prepared by treating a precursor polymeric material with a sulfonyl-containing compound. The precursor polymeric materials are formed from a polymerizable composition that contains a crosslinker that is a free-radically polymerizable spirobisindane monomer. The sulfonyl-containing polymeric material can be used as an ion exchange resin.
