Used in polymer chemistry as a reactive monomer for synthesizing functional hydrogels and biocompatible materials. Its norbornene group enables efficient ring-opening metathesis polymerization (ROMP), allowing precise control over polymer architecture. The polyether chain provides hydrophilicity and flexibility, making it suitable for drug delivery systems and tissue engineering scaffolds. The terminal carboxylic acid allows further conjugation with biomolecules or surface attachment. Commonly applied in developing stimuli-responsive materials and coatings with tailored degradation profiles.
