摘要： A process for producing aliphatic polyester wherein a crystallized aliphatic polyester prepolymer formed from an aliphatic dihydric alcohol and an aliphatic dicarboxylic acid and having a weight-average molecular weight of 2,000 to 100,000 is caused to undergo solid-phase polymerization in the presence of a volatile catalyst to make an aliphatic polyester having a weight-average molecular weight of 50,000 to 1,000,000. This process is more efficient than any prior process calling for a complicated step for catalyst removal, since it enables the removal of the catalyst from the reaction system during and/or after solid-phase polymerization. The polyester is comparable in stability to any aliphatic polyester having any catalyst removed therefrom.
摘要翻译：一种脂肪族聚酯的制造方法，其特征在于，在挥发性催化剂的存在下，使由脂肪族二元醇和脂肪族二羧酸形成的重均分子量为2,000〜100,000的结晶脂肪族聚酯预聚物进行固相聚合得到重均分子量为50,000〜1,000,000的脂肪族聚酯。该方法比任何先前的方法要求复杂的催化剂去除步骤更有效，因为其能够在固相聚合期间和/或之后从反应体系中除去催化剂。聚酯与其中除去任何催化剂的任何脂族聚酯的稳定性相当。
