| Abstract: | A series of novel amphiphilic triblock poly(ethylene glycol)‐b‐poly(2‐aminoethyl methacrylate hydrochloride)‐b‐poly(heptadeca‐fluorodecyl acrylate) (PEG‐b‐PAEMA‐b‐PHFDA) comprised of two hydrophilic PEG and PAEMA segments and one hydrophobic PHFDA segment was designed and synthesized. The structure of the triblock copolymer was characterized by 1H‐NMR and GPC analysis. The amphiphilic triblock copolymer was capable of self‐assembling into liquid‐filled micelles that consisted of PHFDA and liquid perfluorocarbons (PFCs) as the core and PEG as outer shell. PAEMA can be used as cross‐linking sites to increase the stability of the liquid‐filled micelles. The shape, size, and Acoustic properties of the obtained liquid‐filled micelles were investigated. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009 |
