Abstract
The present invention discloses a biodegradable polyester composition, wherein based on a total weight of the biodegradable polyester composition, a weight content of glycidyl methacrylate is 0.05 ppm-10 ppm. In the present invention, by adding a trace amount of glycidyl methacrylate into a chosen formula of the biodegradable polyester composition and controlling the weight content of glycidyl methacrylate which finally remains in the biodegradable polyester composition as 0.05 ppm-10 ppm, a compatibility between aliphatic-aromatic polyester and polylactic acid in the biodegradable polyester composition can be greatly enhanced, which enables the biodegradable polyester composition to have excellent surface property of film material, and no fisheye occurs on the film material because of a fluctuation of processing technique.
