In this research, a novel pyrolysis-gas chromatographic (Py-GC) system combined with a plasma emission detector was developed in order to characterize the molecular structure of various polymeric materials, which were not amenable to conventional spectroscopic methods. Firstly, fundamental characteristics of this system were evaluated using an engineering plastic sample containing halogen in its main chain. As the result, it was proved empirically that this system was a powerful method to identify the peak components on the pyrograms by observing the emission of each element contained in a given sample. Then this method was applied to the structural analysis of the following synthetic polymers and biomaterials :・Determination of stereoregularity of vinyl polymers・Simultaneous determination of end groups and composition of copolymer-type engineering plastics・Determination of lipid components contained in a single zooplankter individualFurthermore, the Py-GC system combined with the temperature-programmable pyrolyzer was also developed as an alternative technique using the conventional pulse-type pyrolyzer. The detailed structural analysis of the natural polymers such as chitin and lignin was carried out by using both methods.

本研究开发了一种新型的裂解气相色谱(Py-GC)系统，该系统与等离子体发射检测器相结合，用于表征各种聚合物材料的分子结构，这是传统光谱方法所不具备的。首先，利用主链上含有卤素的工程塑料样品对该体系的基本特性进行了评价。实验证明，该系统是一种通过观察给定样品中各元素的发射来识别裂解谱峰成分的有效方法。然后将该方法应用于下列合成聚合物和生物材料的结构分析：·测定乙烯基聚合物的立体规整性·同时测定共聚物型工程塑料的端基和组成·测定单个浮游动物体内的脂类组分此外，还发展了Py-GC系统和可编程温度的裂解器，作为传统脉冲式裂解器的替代技术。用这两种方法对甲壳素和木质素等天然聚合物进行了详细的结构分析。
