ABSTRACT:
A method for making an electrolytically conductive battery separator polyethylene film for alkaline battery applications is disclosed which comprises carrying out the grafting reaction in an environment free of air and comprising a pressurized inert gas blanket. The resulting lots of polyethylene film are capable of being made with the range of electrolytic resistance values required for a variety of alkaline battery applications, while exhibiting highly uniform electrolytic resistance characteristics.
