Structure of hyper-branched polyester polyol BOLTORN H2O-COOH. NMR data

The methods of one- and two-dimensional 1H and 13C NMR spectroscopy have been used to study the structure of hyper-branched polyester polyol BOLTORN H2O-COOH and complex Co12[BH20(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.
