title: 1H NMR assignment of oligomeric grafts of maleic anhydride-grafted polyolefin.
abstract: 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 T(2)-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 2.5-3.5 ppm and show broadening.
