Abstract
Methods of making unsaturated modified vegetable oil-based polyols are described. Also described are methods of making oligomeric modified vegetable oil-based polyols. An oligomeric composition having a modified fatty acid triglyceride structure is also described. Also, methods of making a polyol including hydroformylation and hydrogenation of oils in the presence of a catalyst and support are described.
