SUN Da_qing, LI Yan_feng, LIU Li, ZHOU Xiang_dong(Ouhai Dong_bao Chemical Co. Ltd, Wenzhou 325003, China)  
IPDI,tetrahydrofuran polyether, dihydroxymethyl propionic acid, 1,4_butanediol and acetone are put into a 3_mouth flask with a condenser, and stirred at 80℃ for 4h. When the required value of isocyanate (-NCO%) is reached by the help of chemical analysis, the product is cooled, added by aqueous triethanolamine solution and neutralized for 1h, followed by the temperature_raise to leave acetone free by vacuum. The finished product in emulsion is obtained, if the solid contents reach to the theoretic value. Leathers like smooth high gloss corrected grain leather and patent leather finished with the title product give as many as 40000 flexes.
