    • Polyimide of this invention is almost colorless and has remarkably high light transmittance as well as excellent processability and adhesive properties at high temperatures in addition to its substantial high-temperature stability.
      The polyimide is a novel polyimide capable of being used for space and aeronautical materials, electric and electronic members, automotive parts, and furthermore for high-temperature adhesives.
      The polyimide has recurring units of the following formula (I):
      wherein X is a radical selected from the group consisting of a bond, divalent hydrocarbon radical having from 1 to 10 carbons, hexafluorinated isopropylidene radical, carbonyl radical, sulfonyl radical and thio radical, and each nitrogen atom of imide ring is located simultaneously at meta- or para-position to ether linkage.
      The polyimide of this invention is prepared by reacting 4,4ʹ-(p-phenylenedioxy)diphthalic dianhydride with an ether diamine having the following general formula (V):
      and successively imidizing the resultant polyamic acid.
