Abstract

See full text

There are provided aromatic polyester polyol compositions comprising: (i) at least one aromatic acid component; (ii) at least one hydroxylated component; (iii) at least one functionalized natural oil component; and (iv) optionally at least one catalyst component for use in preparing foams. The aromatic polyester polyol compositions can be formed by esterification and/or transesterification. The present technology also provides a polyol blend for use in preparing foams wherein the polyol blend comprises (a) an aromatic polyester polyol formed by an interesterification reaction between (i) a phthalic acid based material; (ii) a hydroxylated material; and (iii) a hydrophobic material, wherein the hydrophobic material is present in an amount of from about 1% to about 50% by weight of the aromatic polyester polyol; and (b) a natural oil based polyol, wherein the hydrophobic material in the aromatic polyester polyol compatibilizes the natural oil based polyol to form a phase stable polyol blend.
