Abstract

The term "Polyurethane" refers to a large group of synthetic organic polymers that have found widespread commercial application in the last two decades. Polyurethanes have the common feature of containing a significant number of urethane HO-(N-C-0)- linkages, regardless of the composition of the rest of the molecule. If one is not familiar with the field of polyurethanes, one might wish to relate them to ethyl carbamate (H2NC00C2H5) which has been knov/n for many years by the simple term "urethane". It is readily apparent, however, that ethyl carbamate is not a precursor of the polyurethanes and that the polyurethanes can not be depolymerized or hydrolyzed to give this compound.
