실험 절차
A 10:1 mole ratio of ethylene carbonate to polyester poly (Formrex® 11-225, a hydroxyl functional diethylene glycol adipate, MW=500, manufactured by Witco) is heated with stirring under a nitrogen atmosphere for 3.5 hours at 175° C. using 0.5 percent sodium stannate trihydrate as catalyst to give 97.3 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 18.7 percent carbon dioxide. The catalyst was removed as in Example 1.
