Abstract

The present invention provides a composition of a modified ethylene-vinyl ester saponified copolymer having an aliphatic polyester grafted thereto, the composition having excellent melt-extrusion moldability. The modified ethylene-vinyl ester saponified copolymer composition of the invention comprises a modified ethylene-vinyl ester saponified copolymer having an aliphatic polyester grafted thereto and at least one metal selected from the group consisting of alkali metal and alkaline earth metal.

Claims (5)

1. A modified ethylene-vinyl ester saponified copolymer resin composition comprising:

a modified ethylene-vinyl ester saponified copolymer (A) having an aliphatic polyester grafted thereto; and

an alkali metal (B).

2. The modified ethylene-vinyl ester saponified copolymer resin composition according to claim 1 , wherein a content of the alkali metal (B) is 10-2,000 ppm by weight of the modified ethylene-vinyl ester saponified copolymer.

3. The modified ethylene-vinyl ester saponified copolymer resin composition according to claim 1 , wherein the metal is contained as a salt.
