Abstract

PURPOSE:To obtain a porous elastomer with high accuracy and at a low cost by soolidifying the porous elstomer impregnated with water or the aqueous solution of paste, through freezing or drying, and working said elastomer to a prescribed form or dimension. CONSTITUTION:A porous elastomer is impregnated with water and frozen and solidified. In other cases, the porous elastomer is impregnated with the aqueous solution of paste, and then dried and solidified. The above-described soldified body is worked to a prescribed form or dimension. In case of freezing solidification after impregnation with water, a desired worked body can be obtained by raising the temperature of the body to the normal temperature after work. In case of drying solidification by the impregnation with paste-containing water, the desired worked body can be obtained by dissolving paste through the immersion into water.
