Abstract
A methacrylate introduced the perfluorooctyl group was synthesised from the 2-(perfluorooctyl) ethanol and dicyclopentadiene. The monomer and 2-(perfluorooctyl) ethyl methacrylate as control were effective for copolymerzation with styrene. Each monomer reactivity ratio were r1=1.35, r2=0.48 and r1=1.22, r2=0.99 (1: styrene) respectively.
Contact angle of water on the coating sample of copolymer with styrene and cured coating sample of unsaturated polyester mixed with the monomer increased as perfluorooctyl group concentration. The former angle increased gradually with perfluorooctyl group concentration, while the latter did rapidly. It supposedly depend on localizing of perfluorooctyl group on the surface because of special properties of fluoro organic compounds.
