Reaction Steps

Ethanolamine, 6.1 g, is added over a 5-10 minute period to half-blocked isophorone diisocyanate, 53.3 g, prepared according to the method of Example VII. During addition of the ethanolamine, the reaction mixture is maintained at a temperature of 90° C. After addition is completed, the reaction mixture is stirred for 3 hours, diluted with the glycol ether ester solvent Ektasolve E.P. (trademark, Eastman Kodak Company, Rochester, N.Y.) 20. g, and then stored. The product oligomer is characterized by its infrared spectrum which shows the absence of the isocyanate absorption at 2250 cm-1, and the presence of urethane and urea carbonyl absorptions in the 1670-1710 cm-1 region.
