Document Type and Number:
WIPO Patent Application WO/2022/202123
Kind Code:
A1
Abstract:
Provided is a block copolymer comprising at least one segment (hereinafter, "ionic segment") containing an ionic group and at least one segment (hereinafter, "non-ionic segment") containing no ionic group, wherein the ionic segment and/or the non-ionic segment has a constituent unit (hereinafter, "constituent unit") that comprises an aromatic hydrocarbon polymer and a first linker that links constituent units together. Thus, the present invention realizes a block copolymer which makes it possible to achieve high proton conductivity even in low humidity conditions, excellent mechanical strength and chemical stability, and improved processability, as well as a polymeric electrolyte material using said block copolymer.
