Abstract: A powder of a barrier material (B) is, after having been melted, applied to a substrate of a polyolefin (A) to give a shaped article, in which the barrier material (B) firmly adheres to the polyolefin (A) even when the surface of the substrate is not subjected to primer treatment. The shaped article is favorable to components to fuel containers, fuel tanks for automobiles, fuel pipes, etc.

Abstract: A powder of a barrier material (B) is after, having been melted, applied to a substrate of a of a polyolefin (A) according to flame spray coating process to give a shaped article, in which the barrier material (B) firmly adheres to the polyolefin (A) even when the surface of the substrate is not subjected to primer treatment. The shaped article is favorable to components to fuel containers, fuel tanks for automobiles, fuel pipes, etc.

Abstract: Multilayer blow molded containers, which comprise a layer of an ethylene-vinyl alcohol copolymer (A) having an ethylene content of 5 to 60% by mol and a degree of saponification of 85% or more and a layer of a resin composition (B), characterized in that the resin composition (B) comprises 1 to 40% by weight of a thermoplastic resin (b1) having at least one functional group selected from the group consisting of boron-containing groups that are convertible to a boronic acid group in the presence of water and a boronic acid group (hereinafter, referred to as a boron-containing functional group), and 60 to 99% by weight of polypropylene (b2), exhibit excellent gas-barrier properties, have good interlayer adhesion, have excellent thermal stability, and are low in production cost.
