ABSTRACT:
A copolymer comprising 10 to 50 mole % of olefin units and 90 to 50 mole % of vinyl units, 50 to 98 mole % of the vinyl units being vinyl alcohol units and 2 to 50 mole % of the vinyl units being vinyl acetal units, is disclosed. This copolymer has excellent resistance to hot water and excellent oxygen barrier property in combination. When this copolymer is subjected to retort-sterilization, blanching is not caused and the excellent oxygen barrier property can be maintained. When this copolymer is laminated on a polyolefin or the like, a laminate structure excellent in the interlaminar peel strength is provided.
