摘　　要：以玉米淀粉、丙烯酰胺、丙烯酸羟乙酯、二甲基二烯丙基氯化铵为原料 ,合成了耐盐性淀粉接枝型高吸水性树脂 ,同时考察了交联剂质量分数和丙烯酸中和度对耐盐、吸水及保湿性能的影响 .结果表明 ,当交联剂质量分数为0 .0 2 % ,丙烯酸中和度控制在 70 %～ 80 %时 ,合成产物吸水率最大 ;所合成的淀粉接枝型高吸水性树脂具有较好的耐酸、碱和盐水的能力 ,并可提高土壤的吸水和保湿性能 ,同时还可降低土壤容重 。A graft copolymer was synthesized by copolymerization of cornstarch with acrylamide, hydroxyl acrylate (HA) and diallyldimethyl ammonium chloride (DMDAAC). The capability of salt\|resisting was studied by acrylate concentration and uniting concentration. Experiments show that the high absorbent resin by starch\|grafting has preferable capability of salt\|resisting, acid resisting and alkali\|resisting. When the additive of joining concentration is 0.02%Wt and the acrylate is counteracted in 70%～80%Wt, the absorbent rate of product is biggest. It has excellent properties for absorbing water and holding water in soil, and could decrease volume weight of soil and adjust air and heat distribution.
