用封闭和开放体系测定了索尔维(Solvay)型催化剂-AlEt_2Cl体系丙烯聚合时温度对聚合速度的影响,测定了反应级数和速度常数,采用下式: E=2.303R log(K_2/K_1)[(T_1·T_2)/(T_2-T_1)] E=2.303R log(V_2/V_1)[(T_1·T_2)/(T_2-T_1)]分别求得了活化能。
The influence of temperature on the polymerization rate of propylene polymerization of Solvay-AlEt_2Cl system was measured by closed and open systems. The reaction order and the rate constant were determined by the following equation: E = 2.303R log (K 2 / K_1 The activation energy was calculated by the following equation: T = T 2 / T 2 = E = 2.303R log V 2 / V 1 T 1 · T 2 / T 2 · T 1.
