Abstract
New polyurethanes with lactone groups in the pendants and main chains were synthesized by the polyaddition of two kinds of L-gulonolactone-derived diols (2,3-O-isopropylidene-L-gulono-1,4-lactone and 5,6-O-isopropylidene-L-gulono-1,4-lactone) with hexamethylene diisocyanate and methyl (S)-2,6-diisocyanatohexanoate and by the subsequent deprotection of isopropylidene groups. They were hydrolyzed more quickly than the polyurethane derived from methyl β-D-glucofuranosidurono-6,3-lactone in a phosphate buffer solution, the pH value of which was 8.0, at 27 °C. © 2002 Wiley Periodicals, Inc.
