The first synthesis of poly(styrene‐co‐styrylethyltrimethoxysilane) [P(ST‐STMS)]‐silica hybrid materials has been achieved via the acid‐catalyzed sol‐gel reactions of P(ST‐STMS) with tetraethyl orthosilicate. New sulfonated polystyrene‐silica hybrid materials have been prepared by sulfonation of P(ST‐STMS)‐silica and poly[styrene‐co‐3‐(trimethoxysilyl)propyl methacrylate]‐silica hybrids with concentrated or fuming sulfuric acid. The sulfonated materials exhibit cation exchange capacities ranging from 0.33 to 1.27 meq/g depending on the composition of the hybrid materials and on the sulfonation conditions. © 1997 John Wiley & Sons, Inc.
