With the aim of identifying the species responsible for initiating epoxy homopolymerization, several BF 3 –amine complexes were synthesized. Their characterization was accomplished by several spectroscopic techniques, notably by 11 B‐NMR. In these polymerizations, the active species appears to be the R–NH + 3 BF − 4salt and not the BF 3 –amine complex. The interactions between BF 3 –amine complexes and the γ–butyrolactone were also studied by FTIR. © 1993 John Wiley & Sons, Inc.
