A poly(vinylcarboxylic acid) and its analogue alkyl ester exhibited significantly different thermal degradation mechanisms under pyrolysis conditions. The greatly enhanced monomer production of poly(alkylvinylcarboxylate) during pyrolysis makes possible qualitative analysis of poly(vinylcarboxylic acid) through its derivatized alkyl ester. In this study, copolymers containing poly(methacrylic acid) and methacrylic acid were used to demonstrate the pyrolysis gas chromatography qualitative analysis of derivatized polymer. The thermal decomposition mechanisms of poly(methacrylic acid), and poly(methyl methacrylate) were studied. The advantages and disadvantages of this derivatized process as related to Py-GC analysis are discussed.
一种聚（乙烯基羧酸）及其类似物烷基酯在热解条件下表现出显著不同的热降解机制。聚（烷基乙烯基羧酸酯）在热解过程中单体产量大幅提高，这使得通过其衍生化的烷基酯对聚（乙烯基羧酸）进行定性分析成为可能。在本研究中，使用含有聚（甲基丙烯酸）和甲基丙烯酸的共聚物来证明衍生化聚合物的热解气相色谱定性分析。研究了聚（甲基丙烯酸）和聚（甲基丙烯酸甲酯）的热分解机制。讨论了这种衍生化过程与热解气相色谱分析相关的优缺点。
