Industrial Applications of STYRENE MALEIC ANHYDRIDE COPOLYMER
| Industry | Application | Process |
|---|---|---|
| Polymer Materials | Synthesis of polymer compatibilizers to improve interfacial compatibility between polystyrene and polar polymers (e.g., nylon, polycarbonate) | Used as a reactive compatibilizer; its anhydride groups undergo ring-opening reactions with terminal amino or hydroxyl groups of polymers |
| Coatings Industry | Formulation of dispersants and thickeners for waterborne coatings to stabilize pigment dispersion systems | Applied as a polymeric surfactant; carboxylate groups generated via hydrolysis of anhydride groups provide electrostatic stabilization |
| Paper Industry | Sizing agent to enhance paper water resistance and strength | Applied as a reactive sizing agent; its anhydride groups esterify with cellulose hydroxyl groups to strengthen bonding |
| Pharmaceuticals | Preparation of drug carriers, e.g., surface modification of nanoparticles | Used as an amphiphilic carrier material; anhydride groups covalently bind to drug molecules or targeting ligands |
| Electronics Industry | Component of photoresists, serving as an alkali-soluble resin | Applied as a film-forming resin; anhydride groups hydrolyze in alkaline developers to yield soluble carboxylate salts |
| Textile Industry | Fiber treatment agent to improve dyeability and antistatic properties of synthetic fibers | Applied as a reactive treatment agent; its anhydride groups form covalent bonds with functional groups on fiber surfaces |
| Adhesives Industry | Formulation of hot-melt adhesives and reactive adhesives to enhance adhesion to metals and polar substrates | Used as a polar tackifier; anhydride groups form ester linkages or hydrogen bonds with hydroxyl groups on substrate surfaces |
