Abstract
PURPOSE: To prepare a swelling polymeric material having excellent water absorption, and useful as a water-absorbent, water-retaining agent, humidity-controlling agent, fire-resisting fire-extinguishing agent, coagulant, sewage-treating agent, etc., by copolymerizing acrylic acid, an alkali acrylate, etc., in aqueous solution.
CONSTITUTION: Acrylic acid is copolymerized with an alkali acrylate and/or ammonium acrylate in water. For example, an aqueous solution of acrylic acid is added with less than equivalent amount of an alkali or ammonia, and subjecting the solution to heat-polymerization, or an aqueous solution containing acrylic acid and more than equivalent amount of an alkali or ammonia is polymerized by heating before the acrylic acid is completely neutralized with the alkali, etc.
