Pyrolysis gas chromatography of polyesterurethanes
The poly(ester urethane) adhesives prepared from polyadipates of ethanediol 1,4-butanediol or 1,6-hexanediol and toluylene diisocyanate and/or diphenylmethane- 4,4-diisocyanate were pyrolyzed at 600°C. The products of thermal decomposition were separated in chromatographic columns filled with Porapak QS, 10% SE-30 on Chromosorb W DMCS or 10% SP-2100 on Chromosorb W AW DMCS. The pyrolysis gas chromatography was a rapid of the investigated polytester urethanes).
