In the present invention, vinylimidazole and [3-(methacryloxy)propyl]trimethoxysilane are copolymerized to form a modified polyvinylimidazole, which then undergoes hydrolysis and condensation reactions with water and tetramethoxysilane to prepare a hybrid of polyvinylimidazole and silica. Experimental analyses show that covalent bondings exist between the modified polyvinylimidazole and silica in the hybrid.

Nella presente invenzione, vinylimidazole e [ 3-(methacryloxy)propyl]trimethoxysilane sono copolymerized per formare un polyvinylimidazole modificato, che allora subisce le reazioni di condensazione e di idrolisi con acqua e tetramethoxysilane per preparare un ibrido di polyvinylimidazole e del silicone. Le analisi sperimentali indicano che i bondings covalenti esistono fra il polyvinylimidazole ed il silicone modificati nell'ibrido.
