摘要
本文研究了聚醚醚酮高温热氧化裂解反应动力学。应用热重分析仪并借助电子计算机测定和计算了聚醚醚酮在空气中热裂解反应的表观活化能ΔE 和频率因子(logA)分别为143.1(KJ·mol^(-1))和15.49(A:min^(-1))。并计算了热寿命估算参数。
A study on the thermo-oxidative decomposition kinetics of polyether ethe- ketone(PEEK) has been done.The values of apparent activation energy(ΔE) and frequency factor(logA) of thermo-oxidative decomposition reaction of PEEK in air were determined by using of thermogravimetric analysis to be 143.1 (kJ.mol^(-1)) and 15.49(A:min^(-1))respectively.Furthemore the thermal lifetime parameters were calculated.
