Abstract
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═C*) in the glycerol fatty acid ester are substituted with a bonding structure selected from the group consisting of: C-*C—C*-C; O-*C—C*-O; C=*C—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.
