用高灵敏度膨胀计和电导测量法研究了苯乙烯-环己烷体系的γ辐射聚合速率。得到了每单位时间溶液中(C)和本体中(C_0)苯乙烯辐射聚合转化百分率之比C/C_0。根据Inokuti关于不同价键电子选择性吸收辐射能量的观点,对单体一溶剂体系的辐射聚合速率进行了理论推导,得到了溶液辐射聚合速率(W)与本体辐射聚合速率(W_0)之比的理论方程和C/C_0的理论方程。理论计算值与实验值比较的结果表明,苯乙烯-环己烷体系溶液辐射聚合动力学符合Inokuti关于选择性吸收辐射能量的观点。
The γ radiation polymerization rate of the styrene-cyclohexane system was investigated using a high-sensitivity dilatometer and conductivity measurement. The ratio C / C_0 of the percent conversion of styrene (C_0) to styrene in the solution per unit time was obtained. According to Inokuti ’s theory of selective absorption of radiant energy by different valence electrons, the radiation polymerization rate of monomer - solvent system was theoretically deduced, and the ratio of solution radiation polymerization rate (W) to bulk radiation polymerization rate (W_0) was obtained Theoretical equation and C / C_0 theoretical equation. The results of theoretical calculations and experimental results show that the radiation polymerization kinetics of the styrene-cyclohexane system is in accordance with Inokuti’s view on the selective absorption of radiant energy.
