5-octafluoropentyl acrylate(OFPA) was conducted at 25℃ in water dispersion system catalyzed and initiated by CuBr/CuBr2/1
10-phenanthroline(phen)/ethyl 2-bromoisobutyrate (EBiB) or CuCl/phen/EBiB in the presence of sodium lauryl sulfonate and sodium perfluorononenyloxyl benzene sulfonate.The results of GPC and 1H-NMR characterization demonstrated that a fluorine-containing block copolymer composed of MMA and OFPA was successfully synthesized in such a water dispersion system.The water-resistance performance of the PMMA film surface was greatly improved when only 2 wt% (based on PMMA) of the resulted fluorine-containing block copolymer was employed as the film surface enhance agent.
