Structure of Hyper-Branched Polyester Polyol BOLTORN H2O-COOH. NMR Data

摘要

The methods of one- and two-dimensional ~1H and ~(13)C NMR spectroscopy have been used to study the structure of hyper-branched polyester polyol BOLTORN H2O-COOH and complex Co_(12)[BH2O(COOH)] on its basis. It was shown that both compounds have non-stereoregular structure. Paramagnetic ions Co(II) are coordinated both on the surface of the molecule and near the core.
