Abstract

Radical polyaddition of bis(α‐trifluoromethyl‐β,β‐difluorovinyl) terephthalate [CF~2~C(CF~3~)OCOC~6~H~4~COOC(CF~3~)CF~2~] (BFP) with 1,4‐dioxane (DOX) was investigated under γ‐rays radiation from a ^60^Co source to produce higher molecular weight polymers compared to those yielded by benzoyl peroxide initiation. Prior to polyaddition, the addition reactions of 2‐benzoxypentafluoropropene [CF~2~C(CF~3~)OCOC~6~H~5~] (BPFP) with tetrahydrofuran (THF) and DOX, and BFP with THF were examined in order to develop probable polyaddition reaction conditions. The polymer bearing 1.5 × 10^4^ as a molecular weight was obtained under the feed molar ratio of DOX/BFP = 16 with an irradiation dose of 2 000 kGy at 40 °C, which is a much higher molecular weight compared to that yielded by benzoyl peroxide.
