Poly(benzyl ether)-b-polystyrene dendritic–linear polymers were successfully synthesized using a dendriticchloric poly(benzyl ether) (G1-Cl, G2-Cl, and G3-Cl) as
the macroinitiator through the atom transfer radical polymerization process. The structure and properties of the resultant polymers were characterizated by gel permeation chromatography, 1H-NMR, Fourier transform IR, thermogravimetric
analysis, and differential scanning calorimetry. It was found that the temperature, reaction time, molar ratio of the macroinitiator to styrene, and the generation number
of the macroinitiator have significant effects on the molecular weights, conversion, and polydispersities of the resultingpolymers. These dendritic–linear block polymers had very good solubility in common organic solvents at room temperature.
The terminal group (dendritic segments) of the polymers can affect their thermal stability. These dendritic–linear polymers after self-assembling in selective solvents
(chloroform/acetone) formed core–shell micelles.
