Abstract

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.

RELATED APPLICATIONS

[0001] This application is a continuation of International application Serial No. PCT / US2008 / 077993 (International Publication No. WO / 2009 / 045926), having an International filing date of Sep. 26, 2008. This PCT application claims priority to U.S. Provisional Application No. 60 / 976,182 filed on Sep. 28, 2007 and U.S. Provisional Application No. 61 / 085,342 filed on Jul. 31, 2008. The entire specifications of the PCT and provisional applications referred to above are hereby incorporated by reference.BACKGROUND OF THE INVENTION

[0002] The use of biorenewable components as substitutes, either in whole or in part, for petrochemical derived raw materials is an emerging trend in the chemical industry. At least one benefit includes the use of a raw material that is non-depleting of fossil resources (i.e. renewable), and in some cases a reduction in lifecycle global warming potential due to the fixation of CO2 in plant biomass from which the biorenewable materials are derived...
