Using paraffin oil as continuous phase, span -80 and tween -80 as compound emulsifying agent, corn starch water- absorbent resin was synthesized with corn starch and acrylic acid by graft co - polymerization in inverse emulsion. The effect of reaction condition on water - absorptivity of the resin, its water absorption kinetics and thermal stability were studied. The result showed that when mass ratio of acrylic acid to starch was 5： 1, volume ratio of oil to water 1.2： 1, initiator agent 2 g, cross -linking agent 0. 175 g, neutralization content of monomer 60% , reaction time 2.5 h, reaction temperature 60 ℃, the maximum of water absorption of the polymer was 70 g/g. The absorbing water process accorded with first order kinetics. The product was of thermal stability.
