ABSTRACT:
A process for the rapid curing of polyurethanes comprising the steps of (a) mixing together a diisocyanate compound, a diol, a polyol, and a diazonium salt and thereafter (b) exposing the resulting mixture to ultraviolet light in the wavelength range of about 2000 to about 4000 Angstroms for a period of about 0.1 second to about 20 minutes at a temperature in the range of about 0.degree. F. to about 180.degree. F.
