Polyvinyl alcohol-based hydrophilic monoliths from water-in-oil high internal phase emulsion template

Super-adsorbent microspheres based on a triallyl isocyanurate–maleic anhydride copolymer for the removal of organic pollutants from water

“…The absorption peak at 1464 cm −1 is due to the nitrogen heterocycle vibrations of N-CvO in the aromatic ring, and that at 930 cm −1 is attributed to the asymmetrical stretching vibration of C-O-C in five-numbered cyclo-maleic anhydride units. [42][43][44][45] Since MAH and TAIC are difficult to be homopolymerized, the appearance of the characteristic absorptions of both TAIC units and MAH units clearly demonstrates the successful copolymerization of TAIC and MAH. Besides, after normalization, the CvO peak height of MAH relative to that of TAIC increases with the decrease of TAIC/MAH.…”
