Molded article and method for production thereof

摘要

Disclosed is a molded article formed from a modified ethylene-vinyl alcohol copolymer (C) The modified ethylene-vinyl alcohol copolymer (C) can be produced by modifying an unmodified ethylene-vinyl alcohol copolymer (A) with an epoxy compound (B) having a double bond, wherein the amount to be modified with the epoxy compound (B) is 0.1 to 10 mol% per monomer unit of the ethylene-vinyl alcohol copolymer (A). In the molded article, at least a part of the modified ethylene-vinyl alcohol copolymer (C) is crosslinked and the gel fraction is 3% by weight or more. The molded article contains little harmful crosslinking agent and is excellent in hot water resistance, heat resistance and gas-barrier properties.
