Tung oil-based polyols were synthesized by the esterification and transesterification between Tung oil-based anhydride and butanediol. The hydroxyl values of the polyols prepared were tested and discussed. Polyurethane was prepared by using Tung oil-based polyols and/or poly(propylene glycol) as polyols and by using isophorone diisocyanate as isocyanate. The effect of the ratio of Tung oil-based polyols to poly(propylene glycol) on the proper-ties of polyurethane prepared was investigated by the water resistance, alcohol resistance and hardness tests. The re-sults show that Tung oil-based polyols are effective to improve the hardness, water resistance and alcohol resistance of polyurethane.
