Nuclear magnetic resonance (NMR) spectroscopy is an important method for materials characterisation and for the study of polymer structure-property relationships. The importance of NMR as a technique arises in part because the signals can be assigned to specific atoms along the polymer backbone and side chains [ 1, 2 ].
