摘　　要：本文研究了淀粉和丙烯酸辐射接枝共聚反应．考察了辐射剂量率、单体浓度、单体配比、单体中和度和淀粉种类对树脂吸水率的影响．结果表明：随着辐射剂量率的上升，树脂吸水率增大；单体浓度增加，吸水率下降；单体配比增加，吸水率先增大，而后下降；中和度增加，吸水率增大；淀粉种类不同，吸水率有所不同．Graft copolymerization of sodium acrylate on starch used radiation technique was investigated. The relations between the absorption capacities of resin and the dose rate, monomer concentration, monomer ratio, the degree of hydrolysis, the type of starch were studied. The result showed the water absorption capacities of the resin increased with the increase of the dose rate and the degree of hydrolysis; when the monomer concentration increased, the absorption capacity of resin decreased. The absorption capacity of resin is associated with monomer ratio and the type of starch.
