Patent ID: 7071250

Claim:
A method for producing an ethylene-vinyl alcohol copolymer resin composition, said method comprising: (a) introducing into an extruder an ethylene-vinyl alcohol copolymer having a water content in a range 0.5–70 wt %, based on the total weight of water and copolymer, and melting said ethylene-vinyl alcohol copolymer having a water content; (b) further introducing into said extruder a liquid component comprising an aqueous solution of a resin, an aqueous dispersion of a resin, an aqueous dispersion of inorganic fine particles having an average diameter of not more than 10 μm, or a mixture thereof; (c) subjecting said melted ethylene-vinyl alcohol copolymer and said component to melt-kneading in said extruder; and (d) discharging the resulting ethylene-vinyl alcohol copolymer resin composition from the extruder.
