| 摘要 |
A resin composition comprising a saponified ethylene/vinyl acetate copolymer (hereinafter referred as "EVOH") (A) having an ethylene content of 20 to 60 % by mole and a degree of saponification of not less than 90 % by mole and, incorporated into the component (A), a boron compound (B) as an indispensable ingredient, acetic acid (C) as an optional component, and at least one compound as an indispensable component selected among acetic acid salts (D) and phosphoric acid compounds (E), the content of each component based on 100 parts by weight of EVOH (A) being 0.001 to 1 part by weight in terms of boron for the boron compound (B), 0 to 0.05 part by weight for acetic acid (C), 0.001 to 0.05 part by weight in terms of metal for the acetic acid salt (D), and 0.0005 to 0.05 part by weight in terms of phosphate group for the phosphoric acid compound (E). This resin composition is typically prepared by bringing EVOH (A) having a water content of 20 to 80 % by weight into contact with an aqueous solution containing the above components, conducting fluidized drying, and then conducting drying at rest.
