标准摘要
[中文适用范围]: 本文件规定了使用热重技术测定聚合物分解的阿伦尼乌斯公式中的活化能 Ea 的方法。 该方法仅适用于反应通过单一机制进行的情况。 如果多级反应由明显分开的单级步骤组成,则它适用于多级反应。 [外文原描述]: This document specifies a method for the determination of the activation energy, E a, in the Arrhenius formula for the decomposition of polymers using a thermogravimetric technique. The method is applicable only if the reaction proceeds by a single mechanism. It is applicable to multistage reactions if they consist of clearly separated single-stage steps.
