SYNTHESIS OF CITRIC ACID-BASED POLYMERS AND THEIR PHYSICO-CHEMICAL PROPERTIES
New monomers, acrylamido-N-methylene-citric and acrylamido-N-citric acids, have been synthesized, and methods have been proposed for the preparation of water-soluble and water-swellable reactive polymers based on them. Certain physicochemical properties of the obtained polymers have been determined. The study of swelling of citric acid-based hydrogels has shown that they exhibit stimulus-sensitive properties.
