Abstract
The present invention provides a hollow molded article container of a liquid polyester resin composition which is superior in moldability, heat resistance, gas barrier properties and gasoline barrier properties. The liquid polyester resin composition comprises a liquid crystal polyester as a component (A) and an epoxy group-containing ethylene copolymer of 50.0 through 99.9% by weight of an ethylene unit (a), 0.1 through 30.0% by weight of an unsaturated carboxylic acid glycidyl ester unit or unsaturated glycidyl ether unit (b) and 0 through 49.9% by weight of an ethylenically unsaturated ester unit (c) as a component (B), wherein the component (A) is 56.0 through 99.0% by weight and the component (B) is 44.0 through 1.0% by weight. The invention also provides a hollow molded article container composed of a laminated structure comprising a layer of the liquid crystal polyester resin composition above and a layer of a thermoplastic resin.
