摘要：Block copolymerization of methyl methacrylate ( MMA) ins and '2, 2, 3, 3, 4, 4, 5, 5-octafluoropentyl acrylate(OFPA) was conducted at 25degreesC 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 H-1-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.
