Abstract

Summary: Stable micelles with polystyrene (PS) as a shell and cross‐linked poly[(acrylic acid)‐co‐(ethylene glycol diacrylate)] as a core have been successfully prepared by reversible addition fragmentation chain transfer (RAFT) copolymerization of acrylic acid and ethylene glycol diacrylate in a selective solvent with PS‐SC(S)Ph as a RAFT agent. For the preparation of stable micelles, the RAFT polymerizations are carried out in different solvents: benzene, cyclohexane, and mixtures of tetrahydrofuran and cyclohexane. The monomer/PS‐SC(S)Ph molar ratio and molecular weight of the macro‐RAFT agent, PS‐SC(S)Ph, influence the RAFT polymerization and the formation of micelles.
