Abstract
In a method of producing an ethylene-carboxylic acid copolymer according to an embodiment of the present invention, a carboxylic acid monomer and a polar co-solvent are introduced separately into a mixing unit or stored together in a supply unit to form a mixture. The mixture and ethylene are injected into a reactor to be copolymerized. Reaction kinetic properties of the carboxylic acid monomer and the polar co-solvent are controlled to suppress a formation of by-products.
