In this article, a series of novel hyperbranched fluorinated polymer with polyglycerol (PG) as the hydrophilic core and poly(2,2,2‐trifluoroethyl methacrylate) (PTFEMA) as solvophobic arms were synthesized. When the atom transfer radical polymerization was carried out using N,N‐dimethylformamide (DMF) as the solvent, [ M ]/[ I ] ratio of 200, and [CuBr]/[ N Br ] ratio of 0.1 at 30 °C, controlled polymerization was achieved. The surface active properties of the polymer at the dimethyl sulfoxide (DMSO)/air and chloroform/water interface were studied by pendant drop measurements. The results showed that the copolymers could reduce surface tension (interfacial tension) in a manner analogous to the conventional surfactant in aqueous solutions. Thermodynamic analysis suggested that the solvophobic PTFEMA chains play an important role in determining the driving force of the aggregate formation in DMSO.
