Abstract: 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.

Abstract: Water-absorbent resins which are prepared by mixing polysaccharides with amino acids (amino acids and/or polymers of amino acids) and heating the mixture so as to cause a crosslinking reaction therein. Each of the water-absorbent resins has a water-absorbing ratio of not less than 10 g/g with respect to physiologic saline as well as having a rate of biodegradability of not less than 10%. Moreover, its water-absorbing ratio under pressure is not less than 10 ml/g with respect to physiologic saline. The water-absorbing ratio under pressure is measured by using a measuring device that is constituted of a weighing machine, a container, an air-intake pipe, a conduit, a glass filter, and a measuring section. The water-absorbent resins are superior in both water-absorbing capacity and biodegradability, and are capable of maintain their water-absorbing capacity even under pressure.
