<p><P>PROBLEM TO BE SOLVED: To provide a blow-molded multilayer bottle with excellent interlayer adhesion and shock resistance even after long-term storage. <P>SOLUTION: The bottle has at least two layers including an ethylene-vinyl alcohol copolymer (A) containing layer obtained by saponifying a copolymer including the following structural unit (1), preferably the copolymer obtained by copolymerizing 3, 4-diacyloxy-1-butene, a vinyl-ester-based monomer and ethylene, and a polyolefin-based resin (B) containing layer. X refers to an arbitrary linkage chain except ether linkage, R1-R4 independently refer to arbitrary substituents, and n refers to 0 or 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
