    • A method for preparing polyester copolymer containing amide link, which can reduce the phase separation of a polyester component and an amide component by improving the compatibility therebetween is disclosed. The method for preparing polyester copolymer comprises the step of polymerizing macrocyclic polyester oligomer and cyclic amide monomer. Wherein, it is preferable that the macrocyclic polyester oligomer is obtained by reacting bis(hydroxyalkyl)ester with dicarboxylic acid chloride in the presence of unhindered amine, and the bis(hydroxyalkyl)ester is obtained by. depolymerizing polyester. resin. Also, lit is preferable that the cyclic amide monomer is E-caprolactam having a cyclic structure and having 2 or more carbon atoms, and the amount of the macrocyclic polyester oligomer is 5 to 99% by weight with respect to total amount of the macrocyclic polyester oligomer and the cyclic amide monomer.
    • 公开了一种制备含有酰胺键的聚酯共聚物的方法,其可通过改善聚酯组分和酰胺组分之间的相容性来降低聚酯组分和酰胺组分的相分离。 制备聚酯共聚物的方法包括聚合大环聚酯低聚物和环酰胺单体的步骤。 其中,优选大环聚酯低聚物是通过使双(羟基烷基)酯与二羧酰氯在不受阻碍的胺存在下反应而获得的,双(羟烷基)酯是通过获得的。 解聚聚酯。 树脂。 此外,点亮的是优选环酰胺单体是具有环状结构且具有2个或更多个碳原子的ε-己内酰胺,并且大环聚酯低聚物的量相对于大环聚酯的总量为5〜99重量% 低聚物和环酰胺单体。
