In this work, we present a novel synthetic route to diblock copolymers based on styrene and 3-vinylpyridine monomers. Surfactant-free water-based reversible addition–fragmentation chain transfer (RAFT) emulsion polymerization of styrene in the presence of the macroRAFT agent poly(3-vinylpyridine) (P3VP) is used to synthesize diblock copolymers with molecular weights of around 60 kDa. The proposed mechanism for the poly(3-vinylpyridine)-block-poly(styrene) (P3VP-b-PS) synthesis is the polymerization-induced self-assembly (PISA) which involves the in situ formation of well-defined micellar nanoscale objects consisting of a PS core and a stabilizing P3VP macroRAFT agent corona. The presented approach shows a well-controlled RAFT polymerization, allowing for the synthesis of diblock copolymers with high monomer conversion. The obtained diblock copolymers display microphase-separated structures according to their composition.

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.
