Description

1,2-Divinylbenzene (CAS No. 1321-74-0) is a high-purity aromatic hydrocarbon compound with the molecular formula C₁₀H₁₀. This reactive monomer is widely used in polymerization processes, particularly in the production of cross-linked polystyrene resins, ion-exchange resins, and specialty polymers. The compound is typically supplied as a mixture of isomers (meta- and para-divinylbenzene) with varying purity levels, often stabilized with inhibitors such as 4-tert-butylcatechol to prevent premature polymerization. Its dual vinyl groups enable efficient cross-linking, making it invaluable for creating three-dimensional polymer networks with enhanced thermal stability and mechanical properties. Suitable for research and industrial applications, our 1,2-Divinylbenzene meets stringent quality standards for use in advanced material synthesis, chromatography media, and specialty coatings.
