A method for producing an ethylene-acrylic acid copolymer may minimize the neck-in phenomenon of the strand by discharging the copolymer strand by controlling the discharging temperature of the produced copolymer to be 200 to 300 C., has excellent workability, processability, and moldability, and melt index (MI) is easy to control. In addition, the ethylene-acrylic acid copolymer produced by this method has the effect of having high melt tension.
