In one embodiment, the monohydroxylated fatty acid/alkyl esters are made by hydroxylating fatty acid/alkyl esters having greater than about ninety-five percent by weight monounsaturation. | 09-23-2010 |
20100267925 | NATURAL OIL-DERIVED POLYESTER POLYOLS AND POLYURETHANES MADE THEREFROM - 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. | 10-21-2010 |
20120136169 | POLYOLS MADE FROM PARTIALLY-EPOXIDIZED, FULLY-HYDROGENATED FATTY ACID ALKYL ESTERS - A method is described for producing polyester polyols by partially-epoxidizing fatty acid alkyl esters having an iodine value from 90 to 190 g I2/100 grams, fully-hydrogenating the partially-epoxidized esters to form hydroxylated fatty acid alkyl esters, and then reacting the hydroxylated fatty acid alkyl esters with a multifunctional ester-reactive initiator compound to form the polyester polyol. | 05-31-2012 |
