One-pot synthesis of poly(N-vinyl pyrrolidone)-b-poly(ε-caprolactone) block copolymers Using a Dual Initiator for RAFT Polymerization and ROP |
| 초록 |
Well-defined amphiphilic poly(N-vinyl pyrrolidone)-b-poly(ε-caprolactone) (PVP-b-PCL) block copolymers were synthesized at 30 oC using 2-hydroxyethyl 2-(ethoxycarbonothioylthio)propanoate (HECP) as a dual initiator for RAFT polymerization and ROP in a one-pot procedure. Hydrophilic PCL blocks were first synthesized via the ROP of ε-caprolactone using diphenyl phosphate as a catalyst followed by the RAFT polymerization of N-vinyl pyrrolidone. This one-pot process is the most convenient method for the synthesis of PVP-b-PCL block copolymers. The PVP-b-PCL block copolymers could be labeled fluorescently through a reaction with rhodamine B isothiocyanate in the same pot. |
