Method for the preparation of high molecular weight oligo(alkylene glycol) functionalized polyisocyanopeptides

摘要

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 isocyanopeptide 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 3 ethylene glycol side chains. The peptides may comprise L aminoacids, D-aminoacids or D, L-aminoacids. The obtained oligoalkylene functionalized polyisocyanopeptides are a new class of materials with unique thermo-responsive properties.
