Synthesis of super absorbent resin and research on its capability

The super absorbent resin from carboxymethyl cellulose grafted polyacrylic acid and pyrrolidone was synthesized with potassium persulphate as an initiator and MBA as crosslink agent by the radical polymerization in aqueous solution.The structure of the graft copolymer was characterized by FTIR.Through the parallel experimental methods,the optimum conditions of polymerization to get high water absorbency was determined.Under these conditions,the absorbency of the obtained resin was 2 339 g/g to the distilled water,110 g/g to the 0.9% NaCl solution.The influence of different conditions on the resin's performance was studied.
