Pyrolysis High-Resolution Gas Chromatography equipped with a Doubleshot Pyrolyzer and a metal capillary column were used in order to identify components of polyurethanes. Polymer glycols used are PTMG, PPG, PEA, PBA, PMPA, PCL and PMVL. TDI, HDI, NDI and MDI as diisocyanates and BD, MOCA, TMP, EDA and HMDA as chain extenders were used. The pyrograms of polyurethanes were compared with the referential pyrograms of polymer glycols, diisocyanates and chain extenders as raw materials in detail. These results showed that the main constituents as raw materials can be identified easily by means of pattern analyses of the pyrograms of polyurethanes.
