Mixtures of aromatic polyols containing amide and ester functionalities suitable for use in rigid foams prepared by reacting a phthalic acid residue with an amino alcohol and subsequent alkoxylation are described. These novel polyols may be blended with conventional polyols to yield rigid foams with better flammability resistance as compared with foams made from conventional polyols alone.
