The 1?H NMR assignment of oligomeric grafts of maleic anhydride (MA)-grafted polyolefin (PO), MA-g-PO hereafter, was experimentally demonstrated for the first time using NMR spectroscopy. 13?C DEPT, 1?H-1?H DQF-COSY, and 1?H?T2-edited spectroscopy of MA-g-PO proved that peaks of the intermediate methine protons of succinic anhydride oligomeric grafts, which are nearly tetrameric, are observed at 2.53.5?ppm and show broadening.
