Several successful examples-where physically sounded kinetic information was obtained from thermoanalytical data in different application fields, such as polymerization of thermosetting resins, biobased polymers and nanocomposites, crystallization and glass transition of semi-crystalline polymers and their nanocomposites-are here presented and discussed. It is explained how the kinetic parameters obtained from advanced isoconversional methods can be interpreted in terms of reaction mechanisms or changes in the rate-limiting step of the overall process, in the case of complex chemical reactions or complex physical transitions, and how these parameters can be used to extract model-fitting parameters.
本文展示并讨论了几个成功的例子，这些例子是在不同应用领域中，从热分析数据获得物理上可靠的动力学信息，如热固性树脂、生物基聚合物和纳米复合材料的聚合反应，半结晶聚合物及其纳米复合材料的结晶和玻璃化转变。本文解释了在复杂化学反应或复杂物理转变的情况下，如何根据反应机理或整个过程中限速步骤的变化来解释从先进的等转化率方法获得的动力学参数，以及如何使用这些参数来提取模型拟合参数。
