Abstract
A combination of catalysts is disclosed as useful to promote the transesterification reaction of an epoxidized soyate with a polyol to yield a high percentage of epoxidized soyate diester with epoxy functionality retained. The primary catalyst is a metallic hydroxide, and the secondary catalyst is a titanate. Bioderived plasticizers useful for thermoplastics and thermosets result.
