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 .
