Abstract

Linear triblock terpolymers of poly(n-butyl methacrylate)-b-poly(methyl methacrylate)-b-poly(2-fluoroethyl methacrylate) (PnBMA-PMMA-P2FEMA) were synthesized by sequential reversible addition fragmentation chain transfer (RAFT) polymerization. Kinetic studies of the homopolymerization of 2FEMA by RAFT polymerization demonstrated controllable characteristics with fairly narrow polydispersities (∼1.30). The resultant PnBMA-PMMA-P2FEMA triblock terpolymers were characterized via 1H NMR, 19F NMR, and gel permeation chromatography. These polymers formed micellar aggregates in a selective solvent mixture. The as-formed micelles were analyzed using scanning electron microscopy and dynamic light scattering. It was found that these terpolymers could directly self-organize into complex micelles in a tetrahydrofuran/methanol mixture with diameters that depended on polymer composition. © 2010 Wiley Periodicals, Inc.
