Method for manufacture of high-expansion type absorbent polymer

摘要: This invention provides a method for the manufacture of high-expansion type absorbent polymer by first causing an which is obtained polymerization monomer and possessed alkali salt acrylic acid as component to be cross-linked at time azeotropic dehydration thereof with cross-linking agent possessing two or more functional groups in presence inorganic subsequently drying polymer. By this invention, there can material absorbs water quickly forms gel not viscid but permeable gas. highly advantageously used sanitary materials free from leaking water-retaining agricultural applications hardly rotton plant roots.
