| 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.
