Macromolecular brushes with thermo-sensitive coil backbones and pendant poly(γ-benzyl-l-glutamate) side chains were synthesized by reversible addition–fragmentation chain transfer and ring-opening polymerization. Functionalization and self-assembly of the macromolecules were investigated.

Copolymer Poly

The block copolymer poly (ε-caprolactone)-b-poly (N-isopropyl acrylamide) (PCL-b-PNIPAM) is synthesized via the combination of ring-opening polymerization (ROP) and reversible addition-fragmentation chain transfer (RAFT). PCL-b-PNIPAM can self-assemble into the micelles taking PCL as the cores and PNIPAM as the shells. Add α-CD into the micelles, because the inclusion complexation of α-CD to PCL chains and phenols is stronger than that to PCL, to regulate the hydrophilic and hydrophobic features of PCL chain. So PCL-b-PNIPAM block copolymers have potential application in drug delivery and gene transfection.

Reversible Addition

A novel zwitterionic triblock copolymer of poly(dimethylamino carbonate)-polycaprolactone-poly((2-(methacryloyloxy)ethyl)dimethyl-(3-sulfopropyl)ammonium) [PAC(DMA)-PCL-PMDMSA] was designed and synthesized via sequential ring-opening polymerization (ROP) and reversible addition-fragmentation chain transfer (RAFT) polymerization successively. The 1H NMR and...
