    • Abstract

       

      The chain flexibility of poly(4-vinylpyridine) was tried to increase by lowering its glass transition temperature (𝑇g) and by increasing its amorphous region by copolymerizing with butyl methacrylate and butylacrylate which act as internal plasticizer. The copolymers were prepared in five different feed molar ratios to optimize the required properties such as higher room temperature conductivity and better film-forming capacity. The conductivity and conduction behaviour of the copolymers, as well as their hydroiodide salts have been reported. There was about 103–104-fold increase in room temperature conductivity of these plasticized polyelectrolytes.
