13-Diisopropenylbenzene is mainly used as a multifunctional monomer and crosslinking agent in polymer and resin production. It is used to improve the strength rigidity thermal stability and dimensional stability of polymeric materials.

Its two reactive isopropenyl groups allow it to form crosslinked polymer networks. This makes it useful for modifying polymer structure and enhancing mechanical and thermal properties.

13-Diisopropenylbenzene is an aromatic hydrocarbon containing a benzene ring with two isopropenyl groups in the meta positions. It is a reactive unsaturated organic compound used primarily in specialty polymer applications.
