The synthesize process for superabsorbent resin was studied, which was the graft copolymerization of acrylic acid(AA) onto starch under microwave radiation. The effects of the processing conditions, such as microwave radiation time, monomer and starch proportion, neutralization degree, initiator amount etc, on absorption power were investigated. Just in 6 min, a superabsorbent resin was synthesized whose absorption power was 753 g/g for deionizing water. The performance test of this resin indicates that its water absorption and retaining power is satisfied. This synthesis process is simple and without waste drainage, it is promising for the cleaner production of superabsorbent resin.
