Abstract: Porous sheet product and methods of making and using the same. In one embodiment, the porous sheet product may be made by a process that includes providing an extrusion mixture, the extrusion mixture including a polymeric binder, a swelling agent, a compatibilizing agent, and a superabsorbent polymer, the superabsorbent polymer being in particle form. The superabsorbent polymer may be wet-milled such that its particle size before and after milling is reduced by a ratio of at least 5:1. The extrusion mixture may be melt-extruded to form a sheet material in film form. At least a portion of the swelling and compatibilizing agents may be removed. The porous sheet product is preferably liquid permeable and may be used, for example, as a battery separator, as a food packaging material, as a diffusion barrier and disposable garments.
