Ab Initio Batch Emulsion RAFT Polymerization of Styrene Mediated by Poly(acrylic acid-b-styrene) Trithiocarbonate

We report an ab initio emulsion reversible addition−fragmentation chain transfer (RAFT) polymerization of styrene using poly(acrylic acid-b-styrene) trithiocarbonate as surfactant and RAFT agent. The system is characteristic of high polymerization rate, controlled polymer molecular weight, and free of coagulum. Design of the amphiphilic RAFT agent is found to be critical for the success. Poly(acrylic acid) neutralization increased the colloidal …
