Beschreibung
Zusammenfassung:	Provided is a saponified ethylene-vinyl acetate copolymer having the advantages of good melt extrusion stability, drawdown resistance, interlayer adhesiveness and gas barrier properties, and its processed products have good surface smoothness. The saponified ethylene-vinyl acetate copolymer contains from 0.1 to.3000 ppm of a compound having a molecular weight of at most 1000 and having at least one conjugated double bond, and has an alkoxyl group content of from 0. 0005 to 1 mol%, an ethylene content of from 5 to 60 mol%, and a degree of saponification of at least 85 mol%.
