N-(p-Ethenyloxyphenyl) carbazole (NEOPC) has been synthesized by etherification of p-bromophenol with vinyl acetate
then p-bromophenyl vinyl ether reacting with carbaxole in the presence of brass power and potassium carbonate at 200℃. The product was identified by elemental analysis
1H NMR
13C NMR and IR spectra. NEOPC is readily polymerized by conventional catalysts of cationic polymerization
such as BF3OEt2
I2
TiCl4
AlCl3
etc. But no polymer was obtained when free radical initiators were used. The rearrangement products and/or the solvent-insoluble products in cationic polymerization of NEOPC. which may be produced by the crosslinking have been discussed.
