Abstract: The invention describes a process for harmonizing the reaction rates for the formation of urethane and isocyanurate groups during the preparation of polyurethane-polyisocyanurate foams by reacting organic polyisocyanates with polyols in the presence of blowing agents and salts of amines having the formula as catalysts, wherein R stands for an hydrogen atom or a straight chained or branched alkyl radical with 1 to 19 carbon atoms, and n and m are equal or different whole numbers from 2 to 10.
