Used as a dispersant and stabilizer in emulsion polymerization processes, helping to control particle size and prevent aggregation. Acts as a compatibilizer in polymer blends, improving interfacial adhesion between dissimilar polymers. Employed in coatings and adhesives for enhanced film formation and substrate wetting. Also utilized in the preparation of functional membranes and as a precursor for further chemical modifications due to reactive pyridine groups.

Additionally, it is employed as an adhesion promoter in composite materials, particularly in coating systems and printing inks, enhancing adhesion between dissimilar layers such as metal-plastic or ceramic-resin interfaces.

In the electronics industry, it is used to control conductivity after chemical modification, making it suitable for sensors and flexible conductive devices.

It serves as a matrix in drug delivery systems for controlled release in biomedical research, responding to environmental changes like pH.

In functional polymer applications, it acts as an adsorbent in separation processes, particularly for removing organic substances or heavy metals from wastewater.
