Document Type and Number:
WIPO Patent Application WO/2019/225731
Kind Code:
A1
Abstract:
The present invention provides: a resin material having excellent hue, water solubility, and viscosity stability in an aqueous solution, the resin material having an ethylene-modified-vinyl-alcohol-based polymer as a main component thereof; and an aqueous solution and an adhesive containing the resin material. The present invention relates to a resin material containing: sodium acetate; and an ethylene-modified-vinyl-alcohol-based polymer having a content ratio of ethylene units of 1 mol% to less than 15 mol%, a viscosity-average polymerization degree of 200 to less than 3000, and a degree of saponification of 80 mol% to less than 99.9 mol% and containing 0.0005 mol% to 0.10 mol% of propyl groups at one terminal end thereof; the content of the sodium acetate being 0.05% by mass to less than 2% by mass.
