摘要:
An improved process to enhance polyurethane foam performance is described. Polyurethane foam is prepared by reactions between a polyisocyanate and a polyfunctional isocyanate-reactive component wherein said reactions are conducted in the presence of catalysts composed of (a) a specific reactive tertiary amine compound selected from the group consisting of bis(dimethylaminopropyl)amino-2-propanol, bis(dimethylaminopropyl)amine, dimethylaminopropyldipropanolamine, bis(dimethylamino)-2-propanol, N,N,N′-trimethyl-N′-hydroxyethyl-bis(aminoethyl)ether and mixtures thereof; and (b) at least one carboxylic acid salt of the specific reactive tertiary amine compound selected from the group consisting of hydroxy-carboxylic acid salts and halo-carboxylic acid salts.
