摘要： 以环戊二烯异丙苯铁六氟磷酸盐为引发剂,用示差扫描量热法研究了氧化环己烯(CHO)阳离子聚合反应动力学.实验结果表明,温度对CHO聚合反应影响很大.CHO在一系列温度下等温聚合时,放热量和转化率均在40℃左右最高,而聚合反应速率则随着温度的升高而降低.CHO聚合反应属一级反应,活化能为-9.87kJ/mol,并对聚合反应历程进行了理论推导,其结果与实验结果相符合.

Abstract: The kinetics of photoinitiated polymerization of cyclohexene oxide (CHO) was studied by using Differential Scanning Calorimeter (DSC).The photoinitiator is a cyclopentadienyl Cumene iron hexafluorophosphate.It is shown that CHOpolymerization is the first order reaction, the activation energy for CHOis -9.87 kJ/mol.Temperature has a marked influence on the polymerization process of CHO.The maximum Hof CHOwas obtained at 40℃, but the maximum of reaction rate was obtained at 27℃.Hand reaction rate drop sharply at elevated temperatures.The initiation mechanism was disclosed by these observations.
