The well‐defined graft copolymer consisting of side chains containing fluorine was synthesized by atom transfer radical polymerization (ATRP) of 2,2,3,3,4,4,5,5‐octafluoropentyl acrylate (OFPA) with the copolymer of styrene and chloromethylstyrene as macroinitiator, which was first synthesized by the nitroxide‐mediated copolymerization of styrene (St) and 4‐chloromethylstyrene (CMS) at 130°C with benzoyl peroxide/4‐hydro‐TEMPO as initiator. These copolymers, i. e. P(St‐co‐CMS) and P(St‐g‐OFPA), were characterized by means of GPC, IR and 1H NMR, respectively. The water contact angles on polystyrene films containing small amount of P(St‐g‐OFPA) as additive were also measured and studied.
