Effect of architecture on the micellar properties of poly (ɛ-caprolactone) containing sulfobetaines

- Various architectures of polymers contained sulfobetaines were successfully synthesized.
- The copolymers can self-assemble into micelles with small size and narrow size distribution.
- The number of arm had a great effect on the micellar properties.
- The core of micelles can efficiently solubilize the hydrophobic drug.
