2‐Propionic‐3‐methyl maleic anhydride methacrylamides (PMMA‐MA) as RAFT polymerizable monomers for the formulation of pH‐sensitive polymers. A) Reaction scheme for polymerizations of PMMA‐MA with a small molecular trithiocarbonate chain transfer agent (TTC‐CTA) or a cholesterol chain transfer agent (chol‐TTC) and the resulting polymers. B) Schematic reaction overview. C) SEC traces of the polymers obtained by the reaction with the TTC‐CTA (analyzed in HFIP (hexafluoroisopropanol) and calibrated with PMMA standards). D) SEC analysis of the polymer obtained by the reaction with the chol‐CTA.
