## Abstract Two new bis(benzylidenephthalide)monomers were synthesized by melt condensation of phenylacetic acid with 3,3′,4,4′‐benzophenonetetracarboxylic dianhydride (BTDA) and with 4,4′‐(hexafluoroisopropylidene)diphthalic anhydride (6FDA). A mixture of three isomers for each monomer was obtaine
