| 摘 要： | 用热重(TG)法研究了双酚A型聚芳醚酮(PAEK)的热分解动力学,计算了热分解动力学参数.结果表明,双酚A型PAEK的热分解符合无规引发分解模型,热分解过程为一级反应.以Kissinger最大失重率法求得热分解反应的反应活化能E为201.909kJ/mol;以Ozawa等失重百分率法求得反应活化能E为211.398kJ/mol;频率因子A值为2.306×10~(14)～9.173×10~(14)min~(-1);预测N_2中267℃失重5%的热老化寿命为10 a.

| Abstract: | The kinetic of thermal degradation of poly ( aryl ether ketone) containing BPA was studied by isothermal and dynamic thermogravimetry. The result calculate from the kinetic model based on random initiation was in good agreement with the experimental data and the thermal degradation was found to be first order reaction. The dynamic data were analysized using Kissinger peak maximum technique, gave apparent global activation energy E of 201. 909 kJ/mol. An isoconversional procedure developed by Ozawa was used,... |
