The types of membranes or separators developed were studied in greater detail with particular emphasis on their permeability to and reaction with silver ions. Further modifications of methyl cellulose formulation were aimed at increased conductivity of electrolyte-swollen films, particularly desirable when the swelling electrolyte is potassium hydroxide in concentrations greater than 30%. Synthesis of new polymers was undertaken to explore the possibility of combining within the same molecule the balance of polarity needed for efficient separator performance.
