Cyclic imides are prepared by the reaction of a bis(dicarboxyphenyl) sulfide or functional derivative thereof, and optionally a second tetracarboxylic acid or functional derivative thereof such as 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride, with a diamine having a spirobiindane nucleus. The cyclic imides may be converted to linear polyimides by reaction with a basic alkali metal sulfide.
