ABSTRACT:
A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and an aromatic diacid ester diol or substituted carbamate thereof. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show excellent resistance to deterioration of physical properties upon humid ageing.
