Document Type and Number:

Japanese Patent JP7276600

Kind Code:

B2

Abstract:

A block copolymer containing one or more segments containing an ionic group (hereinafter referred to as an "ionic segment(s)") and one or more segments containing no ionic group (hereinafter referred to as a "nonionic segment(s)"), wherein at least one of the ionic segment or the nonionic segment contains: constituent units composed of an aromatic hydrocarbon polymer (hereinafter referred to as a "constituent unit"); and a first linker that links the constituent units with each other. A block copolymer and a polymer electrolyte material produced using the block copolymer are made feasible, in which the block copolymer can achieve high proton conductivity under low-humidity conditions, excellent mechanical strength and chemical stability, and enhanced in-process capability.
