Document Type and Number:
WIPO Patent Application WO/2024/024768
Kind Code:
A1
Abstract:
The following is provided as a resin composition in which thickening over time during heating is suppressed. The resin composition contains (A) an ethylene-vinyl alcohol copolymer, (B) a nitrogen-containing compound, (C) an alkaline metal compound, and (D) an alkaline earth metal compound. The content ratio (C/D) of the metal conversion content of (C) the alkaline metal compound relative to the metal conversion content of (D) the alkaline earth metal compound is greater than 0.5. In (B) the nitrogen-containing compound, the number of nitrogen atoms bonded to each carbon atom contained in the structure thereof is two or fewer. Also, the nitrogen-containing compound satisfies (1) and/or (2) below. (1) The molecular weight of (B) the nitrogen-containing compound is 280 or less
(2) The amine equivalent defined by the following equation for (B) the nitrogen-containing compound is less than 225 g/eq
Equation) amine equivalent (g/eq) = the molecular weight of (B) the nitrogen-containing compound / the number of primary amino groups (-NH2) and secondary amino groups (-NH-) present in (B) the nitrogen-containing compound
