An analysis was carried out of degradation products of model compounds polyethylene glycol and ethylene diphenylcarbamate. Pyrolysis has been effected at 350 and 400°C under nitrogen and in vacuo . The products were analyzed by gas chromatography. Aniline, CO 2 , CO, C 2 H 4 , CH 3 CHO, etc., were found.
