Abstract

Official abstract text for this publication.

A resin composition comprises: a modified vinyl alcohol-based polymer (A) containing from 1 to 20 mol % of a structural unit represented by a formula (1) below; and a layered inorganic compound (B). Such a resin composition is excellent in water vapor barrier properties, recyclability, and productivity during coating.

First claim

Opening claim text (preview).

1 . A resin composition comprising: a modified vinyl alcohol-based polymer (A) containing from 1 to 20 mol % of a structural unit represented by a formula (1) below; and a layered inorganic compound (B). 2 . The resin composition according to claim 1 , wherein the modified vinyl alcohol-based polymer (A) contains from 1 to 20 mol % of an ethylene unit. 3 . The resin composition according to claim 1 , wherein a mass ratio (B/A) of the layered inorganic compound (B) to the modified vinyl alcohol-based polymer (A) is from 0.1/100 to 100/100. 4 . The resin composition according to claim 1 , wherein the layered inorganic compound (B) is swelling mica. 5 .
