In this research, a novel pyrolysis-gas chromatography (Py-GC) system combined with reactive pyrolysis in the presence of chemical reagents and/or catalyst was developed in order to characterize the molecular structure of various functional polymers, which were not amenable to conventional spectroscopic methods. As the result, it was proved that this system was a powerful method for the compositional and microstructural characterization of various engineering plastics and natural organic compounds listed below .・determination of end groups and chemical composition of copolymer type polycarbonates (PC)・discriminative analysis of natural resin shellac produced from different countries based on their chemical compositions determined by Py-CG・evaluation of photodegradative changes in chemical structure of silkFurthermore, the reactive Py-GC system using microcapsule, which enabled the pyrolysis of polymer samples under supercritical fluid conditions, was also developed. This system was successfully applied to 1) determination of rosin sizing agents in paper samples and 2) characterization of cross-linking structures in polycabonates.

在这项研究中，一种新的热解-气相色谱（Py-GC）系统结合反应性热解在化学试剂和/或催化剂的存在下，以表征各种功能聚合物的分子结构，这是不服从于传统的光谱方法。结果表明，该系统是一种有效的方法，可用于下列各种工程塑料和天然有机化合物的组成和微观结构表征。·共聚物型聚碳酸酯（PC）的端基和化学组成的测定·基于Py-CG测定的化学组成对不同国家生产的天然树脂虫胶进行鉴别分析·评价蚕丝的化学结构的光降解变化此外，还开发了使用微胶囊的反应Py-GC系统，该系统能够在超临界流体条件下热解聚合物样品。该系统已成功地应用于1）纸张样品中松香施胶剂的测定和2）聚碳酸酯交联结构的表征。
