Provided are a novel polyketone polymerization catalyst and a method of preparing a ligand, which can reduce production costs and can enable commercial mass synthesis by using ((2,2-dimethyl-1,3-dioxane-5,5-diyl)bis(methylene))bis(bis(2-methoxyphenyl)phosphine) as a ligand constituting the polykeytone polymerization catalyst, the ligand having a simple structure and a small molecular weight while having high activity.
本发明提供了一种新型聚酮聚合催化剂及配体的制备方法,通过使用((2,2-二甲基-1,3-二氧六环-5,5-二基)双(亚甲基))双(双(2-甲氧基苯基)膦)作为构成聚酮聚合催化剂的配体,该配体结构简单,分子量小,同时具有高活性,可降低生产成本,实现商业化大规模合成。
