【摘要】 通过热重分析仪研究了TPU/POE的热解动力学,并用多升温速率法中的Kissinger和Ozawa(F-W-O)2种方法计算样品的E,发现除样品POE-MA外,2种方法的结果比较吻合。另外采用单升温速率法研究TPU的热解动力学,并与多升温速率法比较,发现2种方法的结果同样一致。

【Abstract】 The pyrolysis reaction dynamics for a new thermoplastic polyurethane/poly(ethylene-octene)(TPU/POE) blending system was studied by thermogravimetry analyzer(TG).The results showed that the except for the POE-MA,the methods of Kissinger and Ozawa(F-W-O) for E in the multi-heating rate method were compared.Besides,the pyrolysis reaction dynamics of TPU was studied by the single heating rate method,the multi-heating rate method was compared and the result were consistent.
