摘要： A method for producing a porous material by forming a water-in-oil type high internal phase emulsion, which method is characterized by causing waste water generated during the process of production to be put to reuse. The waste water is preferred to be reused after the removal of impurities or the adjustment of pH. According to this invention, the waste water can be reused up to 50 repetitions, with the result that the amount of feed water and the amount of waste water will be decreased. Incidentally, by adjusting the pH of the water-in-oil type high internal phase emulsion after the reaction thereof in the range of 4-9, it is made possible to continue the reuse of waste water and, at the same time, lower the stimulating property of the produced porous material.
