摘要：

The preparation of OSBO tetrablock copolymers using a multistep synthetic procedure was described. The OSBO tetrablock copolymer vesicles were prepared with a microphase-segregated hydrophobic SB core, which comprised of poly(styrene) (S) and poly(butadiene) (B) and equal length hydrophilic poly(ethylene oxide) (O) blocks. It was observed that the dispersion of OSBO in water produced some degree of size control and structural transition as the fraction of O block was increased. The intramolecular symmetry breaking observed provides a powwrful tool for constructing polymersomes with prescribed dimensions and features.
