Abstract
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.
