Abstract
A polymer composition for producing gel extruded articles is described. The polymer composition contains polyethylene particles combined with a plasticizer and one or more shutdown reducing additives. The shutdown reducing additives decrease the shutdown temperature of polymer articles made from the polymer composition. In one embodiment, the polymer composition is used to form a porous membrane for use of a battery separator.
