  • Applications

    1,2-Divinylbenzene (CAS 1321-74-0) is primarily used as a monomer and crosslinking agent in polymer manufacturing, enabling the formation of crosslinked polystyrene and related vinyl-based resins; it is employed to produce ion-exchange resins and polystyrene-divinylbenzene beads used in purification and analytical chromatography; it also serves as a monomer for specialty polymers and coatings and adhesive formulations that require a rigid, crosslinked network; it is used to prepare polymer beads for HPLC columns and other advanced adsorbent materials, with use governed by local regulations and formulation limits.
