摘要

I/HH I1 Bisurethans of the type C~ H~ OC--N-(CHt),--N-COC~ Hs condense with themselves at elevated temperatures in the presence of an alkaline catalyst to yield polymers possessing urea units and dimerized and trimerized isocyanate units. When n= 3, trimethyleneurea is formed, along with the polymer. Structures have been assigned to these condensation products.
