Abstract Spiro(bis)indane bis-oxyphthalic acid bisimides are prepared by the reaction of a nitro- or halo-substituted phthalimide with a salt of a 6,6 min -dihydroxy-3,3,3 min ,3 min -tetramethylspiro(bis)indane. The bisimides may be converted to the corresponding dianhydrides, which react with diamines to form polyetherimides, or to the free tetracarboxylic acids or their salts, esters or amides.
