摘要：
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.
