A method of producing a porous polymeric material having open pores comprises the steps of preparing an emulsion slurry by vigorously agitating a mixture comprising a main ingredient, a polyamide hardener, a filler and water, casting said emulsion slurry in a water-impermeable mold, hardening said slurry while it contains the water. The main ingredient is a bisphenol-type epoxy resin added with one or more reactive diluents each having one or more epoxy rings per molecule and added in an amount of 18 to 50wt%, based on 100 wt% of said bisphenol-type epoxy resin. A large size molded product having a high wet bending strength and a complicated contour can be produced. |
