Abstract
The pyrolysis of ethylene bis(N-phenolcarbamate) was studied as the simplest model of a polyurethane. The degradation occurs by a double process of decomposition involving the simultaneous formation of 3-phenyl-2-oxazolidone, carbon dioxide, and aniline and a partial dissociation into monocarbamate and phenyl isocyanate. Further reaction produces ethylene oxide, N,N′-diphenylethylenediamine, N,N′-diphenyl-2-imidazolidone, and N,N′-diphenylurea.
