The present invention relates to the field of polymer materials and discloses a method for preparing ethylene-vinyl acetate copolymer, the ethylene-vinyl acetate copolymer itself, and its applications. The method comprises: polymerizing ethylene and vinyl acetate in a batch reactor in the presence of an organic peroxide to obtain melt I; melt-blending and pelletizing melt I with an antioxidant in a twin-screw extruder to produce the ethylene-vinyl acetate copolymer. The ethylene-vinyl acetate copolymer prepared using the method provided by the present invention exhibits excellent mechanical properties, fewer crystalline spots, and high transparency. It complies with USP Class VI certification and meets the biocompatibility requirements for medical materials.
