Divinylbenzene (DVB) is a clear yellow liquid with an aromatic odor. DVB is used as a cross-linking agent, meaning it is used to join together individual chains within a polymer. DVB is a mixture of isomers of divinylbenzene and ethylvinylbenzene (EVB, CAS No. 28106-30-1). Jiangsu Andeli manufactures DVB products contain 52-83% of the active cross-linker, respectively.

Product Uses
DVB is a chemical intermediate used to modify the properties of a wide variety of materials. The primary use for DVB is in the production of cross-linked polystyrene resin beads. These styrene DVB copolymer beads are chemically modified to produce ion exchange resins.
Typical applications for DVB:
• Adhesives – improves high-temperature strength of adhesives used to bond aluminum to aluminum, added to caulks and mastics for the

                        construction industry
• Biological – improves physical properties of cell culture micro-carrier beads, incorporated into a hydrogel for slow nutrient release fertilizer
• Catalysis – used in hydrophobic foam catalyst, serves as a catalyst for hydrolyzing nitriles to amides
• Ceramics – improves physical and mechanical properties of fired clay bodies
• Chromatography – used in resins for reversed-phase liquid chromatography and ion exchange chromatography packings
• Coatings – improves surface properties of rubber goods for biomedical applications, used in photocurable protective coatings for wood, metal,

                        glass, and plastic
• Combinatorial chemistry – used to create functionalized copolymers that are useful drug screening tools
• Composite plastics – allows higher production rates, enhanced physical properties, exceptional smoothness
• Elastomers – increases skid-resistance of some rubber compounds, improves adhesion of rubber to steel
• Electrochemical – increases electron sensitivity in electron-beam lithography, improves storage stability of alkaline batteries, improves properties of

                                 electrostatic image toners
• Ion Exchange – used in the production of resin beads that reduce bead swelling, increase bead strength, improve water retention and capacity
• Membranes – used in polymers for electrolysis-diaphragm and piezodialytic-transport membranes
• Optical – used in polymers for ophthalmic and photochromic lenses
• Pharmaceutical – used in polymers for enzyme and coenzyme mobilization, dental cement,and prosthesis materials
• Polymer synthesis – used in polymers for waterproof fabric manufacture, enhanced radiation grafting of polymers, living polymer-polyvinyl

                                     aromatic compound coupler
• Plastics – used extensively as a cross-linker and to aid in copolymerization
• Reprography – used to make copy machine toner resins
• Rubber – used as a processing aid in the extrusion of general-purpose synthetic rubbers
• Star polymers – used in polymers used as motor-oil viscosity modifiers
