摘要
用紫外光（ＵＶ光）引发玉米淀粉与丙烯腈接枝，对影响反应接枝百分率和接枝效率的诸因素进行了研究；对接枝皂化产物进行了吸水性试验；用ＩＲ对接枝产物进行了表征。研究结果表明，对碱糊化玉米淀粉的接枝，单体与淀粉（以脱水葡萄糖单元ＡＧＵ计）摩尔比８，反应时间５０ｍｉｎ，引发剂浓度３．８～７．６×１０－４ｍｏｌ／Ｌ时，其接枝百分率和接枝效率最高。接枝皂化物吸水率达６５０ｇＨ２Ｏ／ｇｓａｍｐｌｅ。
Graft copolymerization of acrylonitrile(AN) onto starch under the irradiation of ultraviolet light(UV light) was studied. Effect of various factors on the percentage of grafting( G %) and the grafting efficiency( E %) were examined. The products were characterized by IR. Saponified starch g PAN is a high water absorbent resin which can absorb as much as 650 times its mass of water.
