The influence of γ‐butyrolactone (γ‐BL), used as solvent of BF 3 ‐amine complexes, on the polymerization of monoepoxides was studied. Different intermediate reaction products of PGE initiated by BF 3 ‐4‐methoxyaniline (BF 3 ‐4MA) previously solubilized in γ‐BL (55% by weight), were separated and analyzed by 1 H‐NMR. It is shown that there is the opening of both epoxy and γ‐BL. The latter does not homopolymerize, but copolymerizes well with epoxy groups. The use of a large quantity of γ‐BL leads to a decreasing molar mass of the formed polymer. The kinetic study allowed to propose the mechanism of the cationic polymerization of epoxy initiated by BF 3 ‐amine complex in the presence of γ‐BL. © 1994 John Wiley & Sons, Inc.
