The characteristic and kinetics of free radical decay in irradiated starch from sweet potato have been investigated by ESR at room temperature. It is found that the relative concentration of free radical is related to the dose. The decay follows second order kinetics at room temperature. The constant of decay and half life of free radical have been obtained.

用ESR方法研究了红薯淀粉在y射线预辐照下,产生的淀粉自由基特性及其室温下的自由基衰减动力学反应。结果表明在室温条件下,淀粉自由基的相对浓度随辐射剂量的增大而增加。自由基相对浓度的室温衰减用二级反应动力学处理,求得了衰减速率常数和淀粉自由基反应的半衰期。

用生物化学发光测量仪(SBL)和顺磁共振仪(EPR)证明了经Co60照射过的淀粉确实能产生淀粉自由基,且随着辐照剂量增加,淀粉自由基的数量增多。同时,SBLI中测得发光值和EPR信号强度随着淀粉自由基存放时间延长而减小和衰减,说明淀粉自由基具有不稳定性。另外,经EPR测定,Co60照射产生的淀粉自由基其特征g值为2.003。

Based on the mechanism of free radical polymerization and graft copolymerization and crosslingking reaction, a water overabsorbent is prepared from starch and acrylamide. Under action of ammonium ceric nitrate as the initiator, the pasting starch forms starch free radical. The graft polymerization occurs between starch free radical and acrylamide. Under the action of N,N’ methylene bis acrylamide as crosslinking agent, the graft product cross links. From which the overabsorbent of water is prepared after...

Based on the mechanism of free radical polymerization and graft copolymerization and crosslingking reaction, a water overabsorbent is prepared from starch and acrylamide. Under action of ammonium ceric nitrate as the initiator, the pasting starch forms starch free radical. The graft polymerization occurs between starch free radical and acrylamide. Under the action of N,N’ methylene bis acrylamide as crosslinking agent, the graft product cross links. From which the overabsorbent of water is prepared after hydrolysis, washing, drying and pulverization. This overabsorbent of water is capabable of absorbing distilled water up to 2 000 times in its saturated state at ambient temperature. It has also excellent performance of water retaining, with a 97% rate of water retaining under the action of centrifugal force.

根据自由基聚合和接枝共聚合、交联反应的机理,淀粉糊化后,在硝酸铈铵作为引发剂的作用下,形成淀粉自由基.它与丙烯酰胺发生接枝共聚反应,并在N,N’-亚甲基双丙烯酰胺作为交联剂的作用下进行接枝交联.接枝交联的产物,经过水解、洗涤、干燥和粉碎制得超吸水剂.籍此探讨交联剂、引发剂、单体与淀粉配比、碱用量等因素对超吸水剂性能的影响.在室温下该超吸水剂在饱和状态可吸2 000 倍的蒸馏水,同时还具有优越的保水性能,能在离心力的作用下具有97% 的保水率.
