As a basic research for development of novel characterization system of organic materials using chemical reactions in the field of supercritical fluid, reactive pyrolysis-gas chromatography in the presence of various chemical reagents, such as tetramethylammonium hydroxide, was applied to compositional and microstructural characterization of various synthetic high-polymers and natural products, as follows :1) Determination of end groups and chemical composition of copolymer type polycarbonates2) Determination of degree of acetylation of chitin/chitosan3) Determination of cross-linking reagent, divinylbenzene in polystyrene-type ion exchange resin precursors with chloromethyl substituents in aiding preliminary reduction of chlorine atoms in the sample4) Determination of short-chain branches in poly(vinyl chloride) and ethylene-vinyl chloride copolymers5) Compositional analysis of polyunsaturated fatty acid oil using trimethylsulfonium hydroxide6) Characterization of Natural Resin Shellac7) Direct determination of a polymeric hindered amine light stabilizer in polypropylene

作为开发利用超临界流体领域中的化学反应的有机材料的新型表征系统的基础研究，在各种化学试剂（例如四甲基氢氧化铵）存在下的反应性热解-气相色谱法被应用于各种合成高分子和天然产物的组成和微观结构表征，如下所示：1）共聚物型聚碳酸酯的端基和化学组成的测定2）甲壳素/壳聚糖的乙酰化度的测定3）交联剂的测定，具有氯甲基取代基的聚苯乙烯型离子交换树脂前体中的二乙烯基苯有助于样品中氯原子的初步还原（氯乙烯）和乙烯-氯乙烯共聚物5）使用三甲基氢氧化锍分析多不饱和脂肪酸油的组成6）天然树脂贝壳的表征7）聚丙烯中高分子受阻胺光稳定剂的直接测定
