A series of novel poly (imino ketone) s (PIK) have been synthesized via palladium-catalyzed polycondensation (Hartwig-Buchwald reaction) of aromatic dichloro or dibromo ketones with various aromatic diamines. The influence of the halogen-containing monomers, concentration, temperature, and catalyst ligands on the polycondensation reaction and on the polymer polydispersity was investigated. These polymers showed good thermal ...
