“…In Figure 3d, the comparison between the ATR FT-IR spectra of mPEG-1900 (black) and the chain-extended polymer (blue) is displayed. Visible is the appearance of a weak signal at 1,645/cm, which can be assigned to the C=C double bond's stretching vibration of the newly added AGE (Gorin et al, 1971). The signal intensity is rather weak, due to the small fraction of the AGE relative to the total structure of the polymer.…”

Herein, a new method to synthesise epoxide-based sequence-controlled polymers via anionic ring-opening monomer addition, a form of anionic ring-opening polymerisation, is presented. This technique allows in combination with post-polymerisation modification (PPM) reactions for the successful preparation of modified mPEG-b-oligo(allyl glycidyl ether) featuring the incorporation of one repeating unit on average at a time. Due to the possible introduction of a vast variety of molecules to the polymeric system via PPM reactions, a multitude of advanced functional polymeric materials can be generated. This, in combination with the chain extension reactions, allows for the synthesis of well-controlled and programmable architectures with particular properties. The structure of the sequence-controlled polymer was confirmed via 1H NMR spectroscopy, size exclusion chromatography, attenuated total reflection Fourier-transform infrared spectroscopy, and differential scanning calorimetry.
