To develop a radical polyaddition reaction of 2‐benzoyloxypentafluoropropene [CF 2 C(CF 3 )‐OCOC 6 H 5 ] (BPFP) with tetrahydrofuran (THF), the reactions of bis(α‐trifluoromethyl‐β‐difluorovinyl) terephthalate [CF 2 C(CF 3 )OCOC 6 H 4 COOC(CF 3 )CF 2 ] (BFP) with THF and of BPFP with 1,4‐dioxane were investigated as model reactions to form 1 : 1 and 1:2 addition products of BFP with THF. This evidenced that THF is monofunctional, and dioxane is bifunctional since the 1:1 and 2:1 addition products of BPFP with dioxane were formed. The polyaddition reaction of BFP with dioxane turned out to produce a white powdery substance which was found to possess a mole ratio of BFP units to dioxane units in the polymers of 1:1. The highest molecular weight obtained was M n = 9.9 × 10 3 .
