Abstract: Provided is a separator including a first layer which consists of a porous polyolefin and a secondary battery utilizing the separator. A first layer exhibits a minimum height equal to or more than 50 cm and equal to or less than 150 cm when a ball having a diameter of 14.3 mm and a weight of 11.9 g located over the first layer is allowed to free fall causing a split in the first layer. A tearing strength of the first layer in a width direction, measured with an Elmendorf tearing method, is equal to or more than 1.5 mN/μm. A tensile elongation of the first layer is equal to or longer than 0.5 mm until a load decreases to 25% of a maximum load in a load-elongation curve in machine direction measured by a rectangular tearing method.

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.
