【 摘 要 】

Hydrogels based on saponified products of poly (acrylonitrile, AN)-starch composites wereprepared, characterized and their water abosrbency properties examined. The term composite refered tothe resultant products of polymerizatin of AN with starch in presence of ceric ammonium nitrate (CAN)as initiator, that is the composite consists of poly(AN)-starch graft copolymer, homopoly(AN) ,oxidized starch and unreacted starch. Thus AN monomer was polymerized with gelatinized starch usingthe ceric ion method. Gelatinization of starch prior to polymerization was affected by heating certainweight of starch in certain volume of distilled water at different temperrature (65, 75 and 85
