Abstract
The investigation on the radical polymerization reactivity of 4-pentenoyloxypentafluoropropene [CH 2 CH–CH 2CH 2–COOC(CF 3) CF 2] (PPF) was carried out since cyclopolymerization of perfluoroisopropenyl vinylacetate [CH 2 CH–CH 2–COOC(CF 3) CF 2] takes place under radical polymerization condition to produce the polymer possessing 5-membered-ring structure in main chain. The soluble polymer of PPF yielded by allyl polymerization bearing 1.8 × 10 4 ( DP ¯ = 78 ) as the highest molecular weight initiated with di-tert-butyl peroxide was produced instead of cyclized polymer bearing 6-membered-ring structure. The polymer possesses perfluoroisopropenyl groups in side chains.
