Used as a functional polymer in coatings and adhesives due to its excellent film-forming properties and adhesion to various substrates. Its pyridine groups enable coordination with metal ions, making it useful in catalysis and metal recovery applications. Employed in gas separation membranes for selective transport of gases like CO₂ owing to polar interactions. Acts as a dispersant and stabilizer in nanoparticle synthesis, preventing aggregation. Applied in controlled release systems and drug delivery where pH-responsive behavior is required, as the pyridine moiety can be protonated in acidic environments. Also utilized in corrosion protection coatings by forming complexes with metal surfaces.
