Solid-phase synthesis on functionalised fluoropolymer resins. Part 2: Preparation and properties of functional Merrifield-type resins possessing a perfluorinated polymer backbone

Monomers alpha,beta,beta-trifluorostyrene and 4-methyl-alpha,beta,beta-trif luorostyrene were prepared and were copolymerised under free-radical emulsi on conditions to give highly stable, well defined lipophilic polymer resins . Benzylic halogenation of the polymer products gave 4-chloromethyl and 4-b romomethyl derivatives which could be elaborated through nucleophilic displ acement of halide. The reaction of 4-fluorophenol with the 4-chloro-methyla ted poly(trifluorostyrene) resin was followed by H-1 and F-19 NMR spectrosc opy and proceeded more rapidly than for Merrifield resin.
