A series of polyisophthalamides and polyisophthalates having perfluorinated side chains were prepared from 5-perfluoroalkylisophthaloyl dichlorides. The aromatic polyamides and polyarylates synthesized by conventional low temperature solution polycondensation and interfacial polycondensation, respec
