Abstract
A method of preparing enhanced reactive vegetable oils wherein the method comprises providing a hydroxy functional vegetable oil having a predetermined hydroxyl value and, under nitrogen, treating the hydroxyl functional vegetable oil with a catalyst using heat and pressure. Any water that is formed is removed. The mixture is heated under pressure and then an alkylene oxide is added while heating under pressure. In one embodiment, thereafter, there is added ethylene oxide and the material is heated and then the material is neutralized with acid. This process results in a primary hydroxyl functional vegetable oil polyol that is an enhanced reactive vegetable oil.
