Thermosensitive PNIPAM-b-HTPB block copolymer micelles: Molecular architectures and camptothecin drug release

- Block copolymers with different molecular architectures were synthesized via ATRP.
- The copolymers exhibited thermo-sensitive self-assembly and CPT release behavior.
- The multiblock copolymers had more regular spherical core-shell micelle architecture.
- The multiblock copolymers had better physicochemical properties and CPT release.
- The copolymer micelles are harmless, and can be employed as drug release carriers.
