This paper introduces the reaction mechanism, process and synthesis of (S-G-PAN) superabsorbent polymer with starch polyacrylonitrile graft copolymer. The water absorption mechanism of superabsorbent resin and the method of measuring water absorption capacity are expounded. The saponification conditions of S-G-PAN copolymer and its effect on water absorption capacity of superabsorbent polymer (H-SPAN) were studied.
