Modified ethylene-vinyl alcoholic resin composition and gas barrier material including layer composed of the same, and method for producing modified ethylene-vinyl alcoholic resin composition

Abstract

To provide a resin composition that exhibits excellent biodegradability, restricts the by-product content to a degree that prevents particle coagulation and blocking in particulate form, and enables stable production of a gas barrier material.SOLUTION: A modified ethylene-vinyl alcoholic resin composition comprises: a modified ethylene-vinyl alcohol resin having a primary hydroxyl group structural unit in its side chain; and a conjugated polyene. The content of an ethylene structural unit in the modified ethylene-vinyl alcoholic resin composition is 2.5-16.5 mol. The content of the conjugated polyene is 0.1-500 ppm relative to the modified ethylene-vinyl alcoholic resin composition. The content of dihydroxyalkyl olefin in the modified ethylene-vinyl alcoholic resin composition is less than 90 ppm.SELECTED DRAWING: None
