Definitions
- the EVOH used in the multilayer container of the present invention is not particularly limited, but has an ethylene content of 5 to 60 mol%, more preferably 23 to 58 mol%, particularly 25 to 55 mol%, and a vinyl acetate component. Having a saponification degree of 90 mol% or more, more preferably 95 mol% or more.
- the ethylene content is 5 mol If the amount is less than 70%, the gas barrier property at high humidity and the melt-molding property are reduced. On the other hand, if it exceeds 70% by mole, sufficient gas barrier property cannot be obtained. However, heat stability, moisture resistance and the like are undesirably reduced.
- dialkyl esters acrylamide, N-alkylacrylamide having 1 to 18 carbon atoms, N, N-dimethylacrylamide, 2-acrylamidopropanesulfonic acid or a salt thereof, acrylamidopropyldimethylamine or a salt thereof, Or acrylamides such as quaternary salts thereof, methacrylamide, N-alkylmethacrylamide having 1 to 18 carbon atoms, N, N-dimethyl Methacrylamide, 2-methacrylamide-propanesulfonyl Methacrylamides such as carboxylic acid or a salt thereof, methacrylamide propyldimethylamine or an acid salt thereof, or a quaternary salt thereof; and N-vinylpyrrolidone, N-vinylformamide, and N-vinylacetamide.
- Vinyl cyanides such as vinylamides, acrylonitrile and methacrylonitrile; vinyl ethers such as alkyl bier ethers having 1 to 18 carbon atoms; hydroxyalkyl vinyl ethers and alkoxyalkyl vinyl ethers; vinyl chloride; vinylidene chloride; vinyl fluoride , Vinyl halides such as vinylidene fluoride and vinyl bromide, vinyl silanes such as trimethoxy vinyl silane, aryl acetate, aryl chloride, aryl alcohol, dimethylaryl alcohol, trimethyl- (3-acrylamide_3-dimethylpropyl) One ann Two Umuku port chloride, and the like Akuriruamido 2-methyl propane sulfonic acid. Further, post-modification such as urethanization, acetalization, and cyanoethylation may be performed without departing from the spirit of the present invention.
- metal salts examples include metal salts of organic acids such as acetic acid, propionic acid, butyric acid, lauric acid, stearic acid, oleic acid, and behenic acid, such as sodium, potassium, calcium, and magnesium; and sulfuric acid.
- metal salts of inorganic acids such as sulfurous acid, carbonic acid, boric acid and phosphoric acid. Preferred are acetates, borates, phosphates and hydrogen phosphates.
- the content of the metal salt is preferably 5 to 100 ppm, more preferably 10 to 500 ppm, particularly preferably 20 to 300 ppm in terms of metal with respect to EVOH. . If the content is less than 5 ppm, the effect of the content may not be sufficiently obtained.
- a) £ 011 having a water content of 20 to 80% by weight is combined with an aqueous solution of a boron compound, an acid and a metal salt.
- a method in which a metal salt is contained and then dried I) After a boron compound, an acid and a metal salt are contained in a homogeneous solution of EVOH (such as a water Z alcohol solution), the mixture is extruded into a coagulated liquid in a strand form.
- a homogeneous solution of EVOH such as a water Z alcohol solution
- ⁇ rays Three rays, ⁇ rays, X rays, electron beams, neutron rays, etc. are used, but ⁇ rays and electron beams are used because they are easy to handle, and ⁇ rays are preferably used in terms of irradiation efficiency.
