The synthesis of block copolymers consisting of nonfunctional and reactive blocks is reported. The precursor polymers are ABA triblock copolymers, consisting of S/VBC or MMA/GMA and prepared via RAFT polymerization. The reactive blocks are converted into blocks with new functionalities that are hard to achieve by direct polymerization. The new polymers are either amphiphilic, with acidic or basic blocks on the outside and a nonfunctional core, or have functionalities that are useful for further reactions like thiol‐ene or alkyne‐azide click reactions. Reaction success and degree of functionalization are determined via FTIR, elemental analysis, and MALDI‐TOF MS. The stability of the RAFT functionalities during the modification reactions is analyzed.
