Synthesis of a Novel Superabsorbent Resin Based on Acrylic Acid and Maleic Anhydride
丙烯酸/马来酸酐高吸水树脂的合成

A kind of novel copolymer superabsorbent resin based on the monomersmaleic anhydride (MA), acrylic acid (AA) and its salts] was prepared by solution polymerization using ammonium persulfate (APS) as initiator, N,N-methylenebisacrylamide (MBA) and glycerine as cross-linking agents. Effects of process parameters such as the concentrations of monomers, cross-linker, initiator and degree of ammoniation of maleic anhydride on the absorbency of superabsorbent resin were discussed. Under the optimal conditions, the absorbency of water from distilled water and 0.9% NaCl solution was 1689 g/g and 115 g/g, respectively.
