<p><P>PROBLEM TO BE SOLVED: To provide an injection-molded article that has excellent barrier properties against gas and fuel and excellent impact strength, and is injection-molded at a high productivity. <P>SOLUTION: This injection-molded article from a modified ethylene-vinyl alcohol copolymer (C) with an ethylene content of 5-55 mol% comprises 0.5-40 mol% of a structural unit represented by formula (I). In the formula, R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>are each a hydrogen atom, a 1-10C aliphatic, 3-10C alicyclic or 6-10C aromatic hydrocarbon group; R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>may be the same with or different from each other; R<SP>3</SP>and R<SP>4</SP>may be bonded together; and R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>may each have a hydroxy group, a carboxylic group or a halogen atom. <P>COPYRIGHT: (C)2004,JPO</p> |
