Abstract

The products of pyrolysis at 300'of the biscarbamates prepared from methylenebis-(4-phenyl isocyanate) and 1-butanol 2, 2-dimethyl-l-propanol and benzyl alcohol, and of the polycarbamate from methylenebis-(4-phenyl isocyanate) arid 1, 6-hexanediol have been determined quantitatively. In all cases carbon dioxide and the parent alcohol or diol were formed. The benzyl biscarbamate and the polycarbamate yielded amine residues, which ...
