Polymeric electrolytes based on vinylpyridines

Homopolymers of 4-vinylpyridine and 2-methyl-5-vinylpyridine and copolymers of 2-methyl-5-vinylpyridine with vinyl chloride and vinyl acetate were prepared by radical copolymerization. Organo-inorganic composites were prepared by hydrolytic polycondensation of the copolymers obtained and tetraethoxysilane. From solutions of the (co)polymers and composites, films were prepared by casting, and their protonic conductivity was determined.
