Method of producing porous synthetic plastic compositions by blending into a polymer at least about 45 volume percent of a plastic-insoluble, water soluble particulate material and a liquid at processing temperatures, capable of forming channels between the solid particles. The blend is then formed into any desired product such as by calendering, extruding or molding and thereafter the water soluble particulate matter and channel forming liquid are leached with water from the product to form a porous plastic.
