Photo-initiated post-polymerization in micellar system of amphiphilic poly(ethylene oxide) macromonomers

Aqueous micellar polymerization of amphiphilic poly(ethylene oxide) macromonomers carrying p‐vinylphenylheptyl end‐group has been found to persist to proceed after turning‐off of the UV‐irradiation. Simulation of the kinetics revealed a high propagation rate constant coupled with a low termination c...

Summary:Aqueous micellar polymerization of amphiphilic poly(ethylene oxide) macromonomers carrying p‐vinylphenylheptyl end‐group has been found to persist to proceed after turning‐off of the UV‐irradiation. Simulation of the kinetics revealed a high propagation rate constant coupled with a low termination constant, supporting a living‐like polymerization at the initial stage. Micellar copolymerization with equimolar styrene also proceeded after UV‐irradiation. Polymer molecular weights in MALLS‐SEC were also found to evolve with time after irradiation.
