  • Publication number: 20240162407
    Abstract: An electrode coating device includes a die block including a first die and a second die coupled to each other, and at least one of the first die and the second die having an accommodating portion for accommodating slurry, a shim plate partially disposed along a circumference of the accommodating portion between the first die and the second die to form a discharge port through which the slurry is discharged, and an expansion plate coupled to the shim plate, wherein the shim plate includes: a first section, second sections, and a third section, wherein the expansion plate is disposed in a form expanding a width of the third section in a region corresponding to the accommodating portion.

  • Patent number: 11685795
    Abstract: In a method of producing an ethylene-carboxylic acid copolymer, a monomer solution containing a carboxylic acid monomer is supplied from a discharging unit. The carboxylic acid monomer is copolymerized with an ethylene-based monomer. A coefficient of friction between the discharging unit and the monomer solution is maintained as 0.3 or less.

  • Publication number: 20220242980
    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.
