Monoepoxy polymerization initiated by BF3‐amine complexes in bulk. II. Influence of water and by‐products on polymer formation

摘要

AbstractThe polymerization of a monoepoxy, phenylglycidylether (PGE), initiated by BF3‐4‐methoxyaniline (BF3‐4MA) was studied at 60°C. The polymerization rate was found to be Rp= kpBF3‐4MA0.53PGE. The improper fraction of BF3‐4MA 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 BF3‐amine complex was proposed. © 1994 Jo
