Abstract

PURPOSE: To manufacture a swelling substance having high water absorbalibity and high water-absorbing and discharging reversibility by adding an aqueous alkali hydroxide or ammonium hydroxide solution to a mixture of acrylic acid and Al (OH)3 and polymerizing.
CONSTITUTION: An aqueous solution of an alkali hydroxide such as NaOH, or ammonium hydroxide is added to a mixture of acrylic acid and Al(OH)3, and then the solution is subjected to a polymerization to obtain a swelling substance having a high water absorbability and a high water-absorbing and-discharging reversibility, usign a comparatively great amount of Al(OH)3 which is inexpensive and free of secondary pollution.
