Notes:
The molecular structures of a series of chain-extended polycaprolactone diols were studied by nuclear magnetic resonance (NMR) and conventional wet chemical techniques. Hydroxyl end group and per cent nitrogen values were obtained by phthalation and automated micro-Dumas techniques, respectively. The value of the NMR technique is demonstrated is demonstrated in providing information regarding the total structure of the polymer. Molecular weight and per cent nitrogen values obtained by this procedure for most samples agree better than 10% with results obtained by the chemical methods.
