Abstract
Novel dibenzylpiperidinium salts with nonnucleophilic anions (DBPi-SbF6, DBPi-PF6) have been prepared as latent cationic initiators. Utility of these salts in the photo and thermal-induced cationic polymerizations of epoxide and vinyl ether monomer systems has been studied. The new initiator, DBPi-SbF6 showed good solubility, high reactivity, and high thermal latency for polymerizations of epoxide and vinyl ether monomers with only 1 wt % of concentration. Cationic polymerization of vinyl ether monomer was significantly faster than epoxide monomer by the synthesized initiators. This article describes the synthesis, characterization, and activity of novel initiators.
