| titleOfInvention | Method for preparing polyester copolymer containing amide link |
| abstract | Disclosed is a method for preparing a polyester copolymer comprising an amide bond, which improves the compatibility of the polyester component with the amide component, thereby reducing the phase separation problem of the two components. The method for producing a polyester copolymer is characterized by polymerizing a macrocyclic polyester oligomer and an amide monomer having a cyclic structure. Here, the macrocyclic polyester oligomer is obtained by reacting a bis (hydroxyalkyl) ester with a dicarboxylic acid chloride in the presence of an unhindered amine, and the bis (hydroxyalkyl) ester is obtained by depolymerizing a polyester polymer. It is preferable. The amide monomer of the cyclic structure is ε-caprolactam having 2 or more carbon atoms of the cyclic structure, and the amount of the microcyclic polyester oligomer is 5 to 5 by weight based on the total weight of the microcyclic polyester oligomer and the cyclic amide monomer. It is preferable that it is 99%. |
