In this paper, the polymerization of tetrahydrofuran (THF) catalyzed by CH_3COBF_4 was introduced. The polymerization mechanism and kinetics of THF were discussed. The calculated apparent activation energy was 71.68 kJ / mol. The polymerization rate constants at 0, 6 and 15 ℃ were 1.18, 2.35 and 6.07 × 10 -3 mol · L-1, respectively. The polymerization rate constant has a significant effect.
