    • A method of removing a residual catalyst metal compound from a polymer solution comprises the steps of: a) mixing a solution in which at least one organic nitrogen compound is dissolved in a polar solvent and the polymer solution to precipitate a chelate compound of the organic nitrogen compounds and the residual catalyst metal compound, b) adding the polar solvent to the solution mixture to dissolve a chelate compound and to precipitate a polymer, and c) filtering the precipitated polymer. After the polymer polymerization is completed, an organic nitrogen compound solution is added to perform a chelate reaction with the residual catalyst metal compound in a solution phase, and the polar solvent is added to precipitate the polymer so that only polymer precipitates are filtered while an additional filtration process in respect to the chelate compound is not performed to easily remove the residual catalyst metal compound.
    • 从聚合物溶液中除去残留的催化剂金属化合物的方法包括以下步骤:a)将其中至少一种有机氮化合物溶解在极性溶剂中的溶液与聚合物溶液混合以沉淀有机氮的螯合化合物 化合物和残留的催化剂金属化合物,b)向溶液混合物中加入极性溶剂以溶解螯合物并沉淀聚合物,和c)过滤沉淀的聚合物。 聚合物聚合完成后,加入有机氮化合物溶液以在溶液相中与残留的催化剂金属化合物进行螯合反应,并加入极性溶剂以沉淀聚合物,使得只有聚合物沉淀物过滤,同时另外 相对于螯合化合物的过滤方法不进行以容易除去残留的催化剂金属化合物。
