Title:
エチレン－ビニルアルコール系共重合体樹脂組成物および多層構造体
Document Type and Number:
Japanese Patent JP7119355
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ethylene-vinyl alcohol copolymer resin composition that has excellent thermal stability, e.g., excellent thermal decomposition resistance, even at high temperatures, and does not discolor or generate odors, even when processed at high temperature.SOLUTION: A resin composition contains an ethylene vinyl alcohol copolymer and a lubricant. At an end structure of the ethylene vinyl alcohol copolymer, the content ratio (Y/Z) of a lactone ring to the total (Z) of a carboxylic acid content (X) and the lactone ring content (Y) is 55 mol% or more. The content ratio of the lubricant to the resin composition is 300 ppm or less in terms of weight.SELECTED DRAWING: None
