Beschreibung
Zusammenfassung:	The present invention provides carbamylation compositions of one or more urea compounds, one or more polyols and a monovalent transition metal or alkali metal catalyst (i), such as lithium ethylhexanoate, which compositions are substantially isocyanate free, enjoy reduced toxicity in comparison to tin catalysts, and which are useful in making polycarbamates which themselves provide compositions for making crosslinked polyurethanes.
