近年来文献上见到一些利用热差分析方法进行反应动力学研究的工作。如Murray等应用这一方法研究粘土的热分解时,得到了一个一級反应的規律;Kissinger利用热差分析方法研究了方解石等的热分解动力学,所得結果与等温法获得的数据相当一致;Borchart等研究了某些偶氮盐的均相分解反应动力学,所得結果与其他方法得到的数据比较,也很符合。类似的研究还見到一些报导。然而,利用热差分析方法研究聚合反应动力学的工作,在文献中尚未見到。本工作报导应用这一方法研究丁二烯在NiAc_2·2Py~(**)-Al(C_2H_5)_2Cl及CoCl_2·4Py-Al(C_2H_5)_2Cl催化系統中聚合动力学的初步結果。
In recent years, the literature has seen some work on the reaction kinetics using the method of thermal analysis. As Murray et al. Applied this method to study the thermal decomposition of clay, a first-order reaction rule was obtained. Kissinger used thermogravimetric analysis to study the thermal decomposition kinetics of calcite and so on. The results obtained are quite consistent with those obtained by the isothermal method. Borchart Et al. Studied the kinetics of the homogeneous decomposition reaction of some azo salts. The obtained results are in good agreement with those obtained by other methods. Similar research also saw some reports. However, the use of thermal analysis method to study polymerization kinetics has not been seen in the literature. This work reports the preliminary results of the polymerization kinetics of butadiene catalyzed by NiAc_2 · 2Py ~ (**) - Al (C_2H_5) _2Cl and CoCl_2 · 4Py-Al (C_2H_5) _2Cl.
