Novel ordered macroporous polymeric gels were derived by chemical modification of the corresponding rigid ones, which were template-synthesized by using silica colloidal crystals. In this study, sulfonated polystyrene ordered macroporous materials were derived from the corresponding rigid polystyrene ones by sulfonation with concentrated sulfuric acid at high temperature. It is key that the sulfuric acid and sulfone groups synchronously introduced are responsible for the hydrogel properties. The ordered morphologies of the samples were confirmed by scanning electron microscopy observation and the replication with titania. Meanwhile, it is demonstrated that the ordered hydrogels can be used as novel templates to prepare mesostructured inorganic materials with tunable morphologies.

Key words: sulfonated polystyrene, ordered macroporous material, hydrogel, template synthesis, chemical modification
