1. Polymers and Functional Materials
Synthesize pH-responsive polymers/hydrogels, acrylic emulsion polymers, and quaternary ammonium products.
Tertiary amine groups on polymer chains protonate under acidic conditions, enabling materials to exhibit intelligent swelling, shrinkage, or charge reversal capabilities. Commonly used in controlled drug delivery and other fields.

2. Pulp and Paper Industry
Surface sizing agents: As cationic monomers, they effectively enhance paper strength, smoothness, and water resistance.

3. Textile Industry
Textile finishing agents, fiber treatment agents Used to improve fabric softness, antistatic properties, or impart specific functionalities.

4. Coatings and Adhesives
Production of specialty coatings and adhesives
Participates in copolymerization to regulate resin adhesion, flexibility, or curing properties.

5. Analytical Separation Techniques
Used in high-performance liquid chromatography (HPLC) analysis
Serves as an analytical target or contributes to developing specific separation and analytical methods.

6. Frontier Scientific Research
Research on supercritical carbon dioxide (scCO₂) systems
Exploring its phase behavior and solubility characteristics in green chemical processes (e.g., supercritical fluid extraction, polymerization).
