Abstract
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.
