Polyurethane foam composition comprising an aromatic polyester polyol compound and products made therefrom

A method of forming a polyurethane foam product comprising:

• reacting, in the presence of a blowing agent, a reactive mixture comprising an isocyanate compound and one or more isocyanate reactive compounds at least one of the isocyanate reactive compounds comprises an aromatic polyester polyol compound comprising an imide moiety wherein the aromatic polyester polyol is the reaction product of:
• (i) a cyclic anhydride compound comprising Structure (1), Structure (2), or combinations thereof;
• Structure (1)
• Structure (2)
• wherein X is a cyclic anhydride moiety, OH, or COOH, which is attached directly to the structure or through R which is an aromatic ring, aliphatic ring, aliphatic chain radical each containing from 1 through 12 carbon atoms with or without alkyl branches, and with or without hetero atoms comprising, O, N, and/or S and n is an integer from 0 through 1;
• (ii) a phthalic acid based compound,
• (iii) a primary amine compound,
• (iv) an aliphatic diol compound;
• (v) optionally, a high functionality, low molecular weight polyether polyol compound;
• (vi) optionally, a hydrophobic compound;
• and
• wherein the weight ratio of Component (i) to Component (ii) is from 1:24 to 24:1;
• and wherein the aromatic polyester polyol is liquid at 25° C. and comprises a hydroxy value ranging from about 30 to about 600.
