    • The present invention relates to a method for separating a catalyst from a solution in which a copolymer and the catalyst are dissolved after performing a copolymerization reaction using the catalyst. More specifically, the present invention relates to section and application of an absorbent used for separation. The present invention provides a method whereby high purity aliphatic polycarbonate is obtained from a reaction product obtained by manufacturing a copolymer using a complex including onium salt as catalyst; and remaining catalyst and byproducts can be effectively separated and recollected. The method for separating the aliphatic polycarbonate polymer and the catalyst during a process of producing the polymer includes the steps of: a) polymerizing carbon dioxide and an epoxide compound in the presence of the catalyst, which is the complex including onium salt; b) separating a reaction mixture obtained by step a) an organic layer from an aqueous solution layer; c) obtaining the aliphatic polycarbonate from the separated organic material layer; and d) recollecting the catalyst from the separated aqueous solution layer.
    • 本发明涉及一种使用该催化剂进行共聚反应后的催化剂与共聚物和催化剂溶解的溶液的分离方法。 更具体地,本发明涉及用于分离的吸收剂的截面和应用。 本发明提供一种高纯度脂肪族聚碳酸酯从通过使用包含鎓盐作为催化剂的络合物制造共聚物而获得的反应产物得到的方法, 并且可以有效地分离和回收剩余的催化剂和副产物。 在制备聚合物的方法中分离脂族聚碳酸酯聚合物和催化剂的方法包括以下步骤:a)在催化剂(其是包括鎓盐的络合物)存在下聚合二氧化碳和环氧化合物; b)将由步骤a)获得的反应混合物与水溶液层分离; c)从分离的有机材料层获得脂族聚碳酸酯; 和d)从分离的水溶液层中回收催化剂。
