Data of One- and Two-Dimensional NMR Spectroscopy in the Study of Structure and Nature of Associations of Hyperbranched Polyester Polyol Boltorn H20-OH

摘要

Structure of the hyperbranched polyester of the polyol BOLTORN H20-OH was studied by one-and two-dimensional ~1H and ~(13)C NMR spectroscopy in combination with the IR spectroscopy and semi-empirical quantum-chemical calculations (method AMI). The polyol structure was shown not to be stereoregular. Three basic types of H-bonding interactions of intra- or intermolecular nature were revealed: C=I···HO, OH···OH, and C=O···HO···HO.
