Abstract
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 macro-initiato, which was first synthesized by the nitroxide-mediated copolymerization of styrene (St) and 4-chloromethylstyrene (CMS) at 130°C with benzozyl 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 1 H NMR, respectively. The water contact angles on polystyrene films containing small amount of P(St-g-OFPA) as additive were also measured and studied.
