Versuchsvorschrift
Ethanolamine, 6.1 g, was added over a 5-10 minute period to half-blocked isophorone diisocyanate, 65.8 g, prepared according to Example I. During addition of the ethanolamine, the reaction mixture was maintained at a temperature of 90° C. After addition was completed, the reaction mixture was stirred for 3 hours, was then diluted with the glycol ether ester solvent Ektasolve E.P. (trademark, Eastman Kodak Company, Rochester, N.Y.), 20 g, and was then stored. The product oligomer was characterized by its infrared spectrum which showed a absence of the absorption at 2250 cm-1, and the presence of urethane and urea carbonyl absorptions in the 1670-1710 cm-1 region.
