Abstract : The polymerization of compounds containing the C=N bond is investigated. Two families of monomers are synthesized, namely imines (azaethylenes) and aza-1,3-dienes. For the imines, electron-accepting substituents such as cyano and carbomethoxy increase the polymerizability of these monomers. Extremely electrophilic imines are not stable, but do polymerize. Among the azadienes, the ones with the N-CN functionality are the most appropriate for polymerization. Substituents increase the stability of these dienes, but on the other hand hinder their polymerization and an exact balance has to be found.... Polymerization, Imine, Azadiene.
