Hello everyone, I synthesized the poly(2-(Methylthio)ethyl methacrylate), According to the papers reported, it can change from thioether (hydrophobic) to sulfoxide (hydrophilic) in the presence of H2O2, so the formed polymer NPs can be dissociated into micelles. But for the polymer synthesized by myself, it showed no responsive to H2O2 (even a very high concentration: 1 M H2O2) from DLS study or NMR. The monomer was purchased from Sigma, and the NMR spectrum was correct as reported. So I do not know why the polymer show no responsive H2O2?
Thank you so much for your attention!

What conditions did you use? If you try to do it in water the reagent may not go into the polymer particles. And the oxidation may give you sulfone.
