説明

<jats:title>ABSTRACT</jats:title><jats:p>Amphiphilic, biocompatible poly(<jats:italic>N</jats:italic>‐vinylpyrrolidone)‐<jats:italic>b</jats:italic>‐poly(<jats:sc>l</jats:sc>‐lactide) (PVP‐<jats:italic>b</jats:italic>‐PLLA) block polymers were synthesized at 60 °C using a hydroxyl‐functionalized <jats:italic>N,N</jats:italic>‐diphenyldithiocarbamate reversible addition–fragmentation chain transfer (RAFT) agent, 2‐hydroxyethyl 2‐(<jats:italic>N,N</jats:italic>‐diphenylcarbamothioylthio)propanoate (HDPCP), as a dual initiator for RAFT polymerization and ring‐opening polymerization (ROP) in a one‐step procedure. 4‐Dimethylamino pyridine was used as the ROP catalyst for <jats:sc>l</jats:sc>‐lactide. The two polymerization reactions proceeded in a controlled manner, but their polymerization rates were affected by the other polymerization process. This one‐step procedure is believed to be the most convenient method for synthesizing PVP‐<jats:italic>b</jats:italic>‐PLLA block copolymers. HDPCP can also be used for the one‐step synthesis of poly(<jats:italic>N</jats:italic>‐vinylcarbazole)‐<jats:italic>b</jats:italic>‐PLLA block copolymers. © 2014 Wiley Periodicals, Inc. J. Polym.
