| 摘 要： | 研究淀粉与丙烯酰胺在60Coγ射线引发下辐照剂量对接枝聚合率的影响。关联得到通用的接枝反应动力学方程式:-ddyt=kI0.5yexp[0.5BI0.5(1-y)];简化得到动力学方程式:-ddyt=0.0192I0.5y exp[I0.5(1-y)],对比试验显示:试验值与理论值吻合性很好。

| Abstract: | Effect of radiation dose on graft copolymerization rate of starch and acrylamide was studied,and kinetics equation for the graft copolymerization was derived as-dy[]dt = kI~(0.5)yexp[0.5BI~(0.5)(1-y).The simplified kinetics equation was-dy[]dt = 0.0192I~(0.5)y exp[I~(0.5)(1-y)].Result showed that the theory data was coincided with that of experiment. |
