Abstract: Provided is a fuel filler pipe including: an inner layer that contains a fluorine-containing copolymer having a carbonyl group-containing group and having a melting point of 250° C. or lower; an intermediate layer that contains a non-fluorine copolymer having a unit based on ethylene and a unit based on vinyl alcohol; and an outer layer that contains a polyolefin, wherein the inner layer, the intermediate layer, and the outer layer are directly laminated in that order, and the outer layer is a layer that contains a polyolefin having a unit based on an acid anhydride or is a layer in which a layer that contains a polyolefin having a unit based on an acid anhydride and a layer that contains a polyolefin having no unit based on an acid anhydride are directly laminated.

Abstract: To provide a polymer alloy excellent in resistance to a high-pressure gas.
A polymer alloy, having a fluorinated copolymer having a carbonyl group-containing group, having a melting point of 250° C. or lower, and at least one thermoplastic polymer selected from the group consisting of a polyamide and an ethylene/vinyl alcohol copolymer, immiscible with the fluorinated copolymer and having a melting point of 250° C. or lower, melt-kneaded,



wherein the proportion of the fluorinated copolymer to the total mass of the polymer alloy is from 10 to 40 mass %, and
particles of the fluorinated copolymer are dispersed in the thermoplastic polymer, and the average particle size of the fluorinated copolymer particles in the polymer alloy is from 0.001 to 10 μm.
