摘要:用 1H- NMR法测定了丙烯酸正丁酯 ( NBA,M1)和甲基丙烯酸正丁酯 ( BMA,M2 )的共聚物组成 ,用 Mayo- Lewis模型的误差变量法 ( EVM)计算出不同温度下该体系本体聚合的竞聚率。并根据 Arrhenius方程计算了该体系均聚、共聚反应频率因子之比 Aii/Aij和活化能之差 Eii-
Bulk copolymerization of n butyl acrylate (NBA, M 1) and n butyl methacrylate (BMA, M 2) were carried out at 60 °C ,100 °C ,120 °C ,140 °C at two sensitive feed compositions. Compositions of the copolymer were analyzed by 1 H NMR and the reactivity ratios were calculated by error in variable method (EVM). The ratios of frequency factors A ii / A ij and the differences of activation energies ( E ii - E ij ) are calculated by Arrhenius equatio...
