A polyester polyol made from natural oil feedstocks is disclosed. Methods for making the polyol are also disclosed. The method comprises reacting hydroxylated fatty acid/alkyl esters with a multifunctional ester-reactive initiator compound to form the polyester polyol. In one embodiment, the hydroxylated fatty acid/alkyl esters are made by hydroxylating fatty acid/alkyl esters having up to ninety-five percent by weight monounsaturation.

Enhanced oligomeric polyols are reported. The enhanced oligomeric polyols may be prepared by a method comprising the steps of: (a) providing an oligomeric polyol that comprises at least one glycerol fatty acid ester having at least one glycerol fatty acid ester bond; wherein at least 5% of the ethyldenyl groups (*C&#x2550;C*) in the glycerol fatty acid ester are substituted with a bonding structure selected from the group consisting of: C-*C&#x2014;C*-C; O-*C&#x2014;C*-O; C=*C&#x2014;C*-C, and mixtures thereof, where * is used to denote the original carbon atoms in the ethylidenyl group; and (b) cleaving at least a portion of the glycerol fatty acid ester bonds to form the enhanced oligomeric polyol. The enhanced oligomeric polyols are useful in making polymers such as polyurethanes.

The invention relates to polyurethane foams comprising oligomeric polyols. In embodiments of the invention, the polyurethane foams comprise the reaction product of: (a) a polyisocyanate; and (b) an active-hydrogen containing composition comprising an oligomeric polyol having a hydroxyl number of about 45 to about 65 mg KOH/g, a number average hydroxyl functionality (Fn) of less than about 2.7, and about 40% weight or greater oligomers. The polyurethane foams of the invention may be slabstock foams or molded foams. Also disclosed are low odor polyols and polyurethane compositions.
