METHOD OF SYNTHESIS OF POLYMERS EXHIBITING HIGH WATER ABSORPTION Russian patent published in 1997 - IPC

Abstract RU 2083596 C1

FIELD: chemical technology, polymers. SUBSTANCE: polymers were synthesized by polymerization of 40-60% acrylic acid an aqueous solution or its mixture with 1-50 mole% methacrylic acid neutralized by 50-90% with alkaline metal or ammonium hydroxide in the presence of cross-linking agent taken from the group involving derivatives of triethanolamine and polyethylene glycol, N, N'-methylene-bis-(meth)acrylamide. Polymerization is carried out in quasihermetic thin layer at 50-90 C. EFFECT: improved method of synthesis. 1 tbl
