Document Type and Number:
WIPO Patent Application WO/2014/034760
Kind Code:
A1
Abstract:
A polyimide which contains a repeating unit represented by general formula (1) and/or a repeating unit represented by general formula (2) [wherein R1, R2 and R3 independently represent a hydrogen atom or the like; R4 represents an aryl group having 6 to 40 carbon atoms; and n represents an integer of 0 to 12], wherein the ratio of the total amount of the repeating unit represented by general formula (1) and the repeating unit represented by general formula (2) to the total amount of all of repeating units is 90 mol% or more.
