The authors studied on the surface treatment of stainless steel for forming adherent film of polymer on the electrode with methyl methacrylate, of which the polymerization was initiated at the electrode. Formation of an efficient film was observed in the system of (methyl methacrylate-N, N-dimethyl formamide-sodium nitrate) for a defined time of electrolysis and current density. However, formation of a deliquescent film was observed under a certain condition. Probably, it would be caused by the deposition of supporting electrolyte as it was or as an different kind of salt. The time of electrolysis had effects on the structure of the film. A proper time of electrolysis was required for forming an efficient adherent film.The authors examined and failed in the formation of polymer film whith a different system of (dichloromethane-tetraethyl ammonium-p-toluene sulfonate-methyl methacrylate).
