Abstract
Model urethanes of phenol and bisphenol were synthesized, and their thermal dissociation was studied. The thermodynamic parameters of dissociation were determined. These studies have been extended to cover two polyurethane polymers in order to determine the number of urethane bonds cut. Some comments are also made on the trapping of liberated isocyanate.
