A new glycomonomer, 3-acrylamido-3-deoxy-1,2:5,6-di-O-isopropylidene-a-D-glucofuranose, was synthesized from D-glucose. This monomer was homopolymerized and copolymerized with N-isopropylacrylamide in different compositions by free-radical polymerization. The composition of the copolymer was determined with 1 H-NMR spectroscopy. On acid hydrolysis, water-soluble deprotected copolymers were obtained. The protected and deprotected copolymers showed a sharp cloud-point temperature. A linear correlation was obtained between the lower critical solution temperatures and the concentration of glycomonomer in the copolymers V
