Abstract
A method of preparing a rigid cellular polyurethane comprising reacting a polyalkylene polyol having at least two active hydrogen atoms with an organic polyfunctional isocyanate, said reaction being carried out in the presence of at least one member of the group consisting of in 1,3,5-tris- (N, N-dialcohilaminoalcohil) -hexahidrotriazina, and 2,4,6-tris- (N, N-dialcohilaminoalcohil) -phenols and their adducts with alcoholic oxide, and at least one member of the group consisting of carboxylic acids having 2 to 19 carbon atoms and alkali metal salts thereof.
