'''Polyimide''' (sometimes abbreviated '''PI''') is a [[monomer]] containing [[imide]] groups belonging to the class of [[high-performance plastics]]. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, such as high temperature [[fuel cell]]s, displays, and various military roles.  A classic polyimide is [[Kapton]], which is produced by condensation of [[pyromellitic dianhydride]] and [[4,4'-oxydianiline]].<ref name=Ullmann>Wright, Walter W. and Hallden-Abberton, Michael (2002) "Polyimides" in ''Ullmann's Encyclopedia of Industrial Chemistry'', Wiley-VCH, Weinheim. {{doi|10.1002/14356007.a21_253}}</ref>
