PHASE-REVERSIBLE HYDROGELS BASED ON ACRYL AMIDE-N-(2-D-GLUCOSE)ACRYLAMIDE COPOLYMERS

The copolymers of acrylamide with N-(2-D-glucose)acrylamide were synth esized. It was shown that the reaction of these copolymers with concan avalin A yields hydrogels, whose degree of swelling is controlled by t he molar ratio between the units of N-(2-D-glucose)acrylamide and conc anavalin A. For the reaction of the resulting hydrogels with a glucose solution, it was found that there exists a threshold concentration of glucose, above which the hydrogel transforms quickly into a soluble s tate.
