Outline of Final Research Achievements |
To develop a unique thermochemolysis technique essential for a novel pyrolyzer to analyze whole chemical structures in advanced polymeric materials, the conversion reactions of thermocured phenol resins in tetralin were investigated in detail. The cured phenol resins were completely liquefied in tetralin at 450-500 ºC. The decomposition products were proved to reflect the cross-linking structure of the cured phenol resins and useful for the structural analysis of the cured resin samples. On the other hand, the reliable identification of the pyrolysis products should be essential to analyze whole chemical structures in advanced polymeric materials. For this purpose, a new pyrolysis-GC-MS system using atmospheric pressure chemical ionization combined with quadrupole time-of-flight mass spectrometer was examined in terms of the characterization of chain ends structure in polymer materials and the specific pyrolyzates were able to be selectively detected and exclusively identified.

Academic Significance and Societal Importance of the Research Achievements |
各種ポリマー材料、中でも各種熱・光硬化樹脂に代表される架橋ネットワークポリマーは、塗料、電気・電子部品、歯科補強材料など、身近な製品として幅広く用いられてきた。さらに、最近ではフォトレジスト材料や3Dプリンティング素材など、科学の最先端分野でも広く利用されている。したがって、これら架橋高分子材料の物性や特性に密接に関連した三次元ネットワークの解析は、最先端の基礎高分子科学の分野のみならず、これらに関連した産業界においても大きな課題となっている。本研究の成果は、こうした課題の解決に資するものである。
