Two diisocyanate monomers containing methylene groups and built-in imide structure have been prepared from the parent diacids via the CurtiusΒ±Weinstock rearrangement. Polyimides have been synthesized by solution polymerization of these isocyanates with pyromellitic dianhydride (PMDA), 3,3',4,4'-benz
