The polymerization of a monoepoxy, phenylglycidylether (PGE), initiated by BF 3 ‐4‐methoxyaniline (BF 3 ‐4MA) was studied at 60°C. The polymerization rate was found to be R p = k p [BF 3 ‐4MA] 0.53 [PGE]. The improper fraction of BF 3 ‐4MA shows the complexity of the polymerization mechanism. Moreover, the influence of water, temperature, by‐products formed during the polymerization, on the kinetics of PGE was also examined. Furthermore, two other monoepoxy monomers, glycidylmethacrylate (GMA) and α‐napthylglycidylether (NGE), were studied for the comparison with PGE. Finally, an overall mechanism of the cationic polymerization of epoxy by BF 3 ‐amine complex was proposed. © 1994 John Wiley & Sons, Inc.
