## Abstract New polymerโforming monomers, 3โbenzylideneโ5โchloroformylphthalide and 3โbenzylideneโ6โchloroformylphthalide, were synthesized by the Perkin reaction of trimellitic anhydride with phenylacetic acid, followed by chlorination. The polycondensation of these monomers with aromatic diamines
