Abstract:
A polyester composition, includes an aliphatic polyester and an aliphatic-aromatic copolyester. The aliphatic-aromatic copolyester is a copolymer having a repeating unit A and a repeating unit B. The preparation method for the polyester composition includes the steps of mixing all the components having the aliphatic polyester and the aliphatic-aromatic copolyester, and subjecting the resulting mixture to extrusion granulation.
