【Abstract】 Polyester polyalcohol is prepared by using diglycol in place of polyalcohol, reacting with adipic acid. Then polyester adhesive reagent is manufactured by using polyester polyalcoholand the proper ratio of OH/NCO and vulcabond (TDI). This method has good virtue of low cost and high viscosity which can compete with similar products. Besides, we make use of diglycol, abyproduct from glycol preparation.更多还原
