Abstract:This article focuses on the structural analysis of polyhydroxyurethane obtained by the reaction of 2,2‐bisp‐(1,3‐dioxolan‐2‐one‐4‐yl‐methoxy)phenyl]propane with a diamine based on the model reaction. The compounds obtained in the model reaction could be separated into hydroxyurethanes containing primary and secondary alcohol groups by preparative gel permeation chromatography with a recycling technique to determine the structures by 1H NMR, 13C NMR, distortionless enhancement by polarization transfer (DEPT) and C H correlation spectroscopy to obtain hydroxyurethane carrying the primary alcohol structure moiety dominantly. The ratios were independent of the reaction temperature but somewhat dependent on the solvents and amines. © 2001 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 39: 851–859, 2001
