高分子物質의 熱分解에 關한 硏究 (第2報) Gas Chromatography 에 依한 熱分解生成物의 檢索 = On the Pyrolysis of Polymers II. Identification of the Products from Polymer Pyrolysis by Gas Chromatography

다국어 초록 (Multilingual Abstract)

The products from polymer pyrolysis at $450^{\circ}$ are cooled with ice, then liquid and gaseous portions are analysed by gas chromatography. Di-2-ethyl hexyl sebacate column, silicone oil column, silica gel column and tetraethyleneglycol dimethylether column, which was most effective for the separation of hydrocarbon gases, are used. Identification of isomers could be secured more effectively by gas chromatography than mass spectrometry. Elucidation of the mechanism for thermal decomposition of polymers could be done through the identification of pyrolysis products. Although more extensive work is needed, some patterns of polymer pyrolysis are discussed.
