摘要
采用自由基聚合法、过硫酸钾为引发剂，通过马铃薯淀粉与丙烯酸及其钠盐的自由基接枝共聚合成高吸水剂。对淀粉糊化用水量对产品吸水性能的影响进行了研究．结果表明，在马铃薯淀粉与纯水的配比为1：5时进行糊化，可获得吸水性能最佳的产品，产品吸水量高达1400～1600g／g。
Super absorbent polymer （SAP） was synthesized by graft eopolymerizing of the potato starch with acrylic acid and sodium acrylate in presence of potassium supersulphate as initiator. This article reviews on the influence of starch gelatinization water-consumption to the water absorbability of SAP. The results of the experiments show that we can obtain the products with highest water absorbability and cost effective, when the contents of potato starch and distilled water is 1 ： 5.
