Latest Patents

Douglas holds a patent for the "Esterification of Rosin." This patent discloses a method for esterifying rosins with a polyol. The process involves contacting rosin with the polyol in the presence of a bleaching mixture that includes both an alkaline earth hypophosphite and hypophosphorous acid. The method enables the production of rosin esters with a color of less than about 5 Gardner neat. The preferred bleaching mixture consists of 0.01% to 0.10% of alkaline earth hypophosphite and 0.10% to 0.15% of active hypophosphorous acid, based on the weight of the rosin. The most preferred alkaline earth hypophosphite is calcium hypophosphite. Additionally, the patent describes a method for preparing an adhesive from the rosin ester.
