METHOD OF SYNTHESIS OF RARE-CROSS-LINKED ACRYLIC ACID POLYMERS Russian patent published in 1997 - IPC

Abstract RU 2088598 C1

FIELD: polymers. SUBSTANCE: method involves polymerization of 5-25 wt. -% acrylic acid in inert solvent in the presence of 0.01-2.5 wt.-% initiating agent of free-radical polymerization and 0.01-0.5 wt.-% cross-linking agent. Polymerization is carried out at temperature by 3-10 C above that of inert solvent boiling point. Product is used for preparing highly viscous clear gels used in medicinal, pharmaceutical, perfume-cosmetic industries and domestic chemistry. EFFECT: improved method of synthesis. 1 tbl
