Polyurethanes have been prepared from the reactions of the diimidazole and ditriazole adducts of 2,4‐toluene diisocyanate and ethylene glycol or polyols. Suitable formulations have been developed from these components which are useful in preparing polyurethane coatings and foams. Imidazole was established as an effective catalyst for the reactions of the diphenol adduct of 2,4‐toluene diisocyanate with polyols. Imidazolecatalyzed polyurethane formation from the phenol‐blocked diisocyanate occurs readily between 100° and 140°C. A mechanism for the catalytic activity of imidazole in these reactions is proposed. Copyright © 1972 John Wiley & Sons, Inc.
