摘要： 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.
