The Effect of an Oxidative-Caustic Environment on Graft Copolymer Membranes
This paper discusses the accumulated results of a continuing study on the long-term effect of the environment in a Ag-Zn battery on a separator material prepared from thin films of crosslinked polyethylene grafted with poly (potassium acrylate), the acrylate content being usually approximately 40 wt % These materials have been prepared for JPL by Southwest Research Institute, San Antonio, Texas (Ref. l). This type of separator membrane is considered for spacecraft applications because of its relative stability and the ability to withstand heat sterilization at 135°C.
