Divinylbenzene
Divinylbenzene (CAS: 1321-74-0, C<sub>6</sub>H<sub>4</sub>(CH=CH<sub>2</sub>)<sub>2</sub>) is a versatile aromatic hydrocarbon with a molecular weight of 130.19 g/mol. It is a key crosslinking agent and monomer used in the synthesis of polymers and resins. Its difunctional nature allows it to create robust three-dimensional networks, enhancing the physical and chemical properties of various materials. Commonly employed in ion-exchange resins, specialty polymers, and as a comonomer in styrene-butadiene rubber production.
Crosslinking Agent in Polymer Synthesis
Divinylbenzene is extensively used as a crosslinking agent in the production of polymers like polystyrene and polyacrylates. It facilitates the formation of rigid, insoluble polymer networks, crucial for applications such as ion-exchange resins and chromatographic supports.
Monomer for Specialty Resins
As a difunctional monomer, divinylbenzene polymerises with other monomers to create specialty resins. These materials find use in coatings, adhesives, and composite materials, benefiting from the enhanced thermal and mechanical stability imparted by the crosslinked structure.
Component in Ion-Exchange Resins
The ability of divinylbenzene to form highly crosslinked structures makes it an essential component in the manufacture of ion-exchange resins. These resins are vital for water purification, chemical separation, and catalysis.
Modifier for Elastomers
Divinylbenzene can be incorporated as a comonomer in the production of elastomers to modify their properties. It can improve heat resistance, reduce creep, and enhance the overall mechanical integrity of rubber compounds.
