The development of new and improved manufacturing methods, controls, equipment and processes was directed toward the generation of methacrylic acid- grafted- polyethylene film for use as a superior alkaline battery separator material. This material is of interest to the Air Force as a means of significantly increasing the life and performance of secondary nickel-cadmium and silver-zinc alkaline aircraft batteries and thus accomplish meaningful cost savings. Technology was developed to permit design of equipment for large scale production of the separator material. Prototype or pilot equipment for each phase was constructed and operated to establish optimum operating conditions and to determine process controls. Limitations on processing steps such as, film extrusion, crosslinking, grafting, washing, converting and packaging were established.
