ATRP synthesis of ABC lipophilic-hydrophilic-fluorophilic triblock copolymers

New ABC triblock copolymers that contain lipophilic, hydrophilic, and fluorophilic blocks are reported. These new block copolymers were synthesized via sequential controlled/living atom transfer radical polymerization. The formation of block copolymers was confirmed by size exclusion chromatography, H-1, and F-19 NMR. In direct comparison to the ABC copolymer, the corresponding ABA' polymer did not produce a gel up to 45 wt % polymer. (c) 2007 Wiley Periodicals, Inc.
