Abstract: The present invention relates to a process for the preparation of oligo(alkylene glycol)-functionalized polyisocyanopeptides comprising the steps of functionalizing an isocyanopeptide with oligo-(alkylene glycol) side chains and subsequently polymerizing the oligo-alkylene glycol-functionalized isocyanopeptides. Several isocyanopeptides may be functionalized with various linear or non-linear oligo-(alkylene glycol) side chains having variable chain length. The alkylene glycol may be selected from the group consisting of ethylene-, propylene-, butylene- or pentylene glycol. Preferably, the isocyanopeptides are functionalized with at least three ethylene glycol side chains. The peptides may comprise L-amino acids, D-amino acids or D, L-amino acids. The obtained oligoalkylene-functionalized polyisocyanopeptides are a new class of materials with unique thermo-responsive properties.
