Abstract:
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.
