DBI has two double-bonds at the position of α and β. It is generally consider as substitutive derivative of acrylate. Because of it’s active reaction character, it can be used in many area.
DBI is mainly used as monomer of macromolecule material, copolymer and midbody of organic synthesis. It can be used by itself to prepare macromolecule materials, the polymer liquid can be used as plasticizing agent for PVC. But mostly, it is used as internal-plasticizing agent, when copolymerizing with styrene, acrylic nitrile, acrylate or vinyl chloride, to improve the copolymer performance, such as plasticization and water-solubility. Those polymers are usually used for water-based resin (water-based printing ink, electropositive coating, baking finish for metal), molding material, coating material, fiber, film finishing agent, lubricant and its addition agent, adhesive, ion exchange resin, and so on.
DBI has little performance of self polymerization, but can hardly polymerize without activator. Peroxide, oxidation-deoxidization activator or UV light may lead it to self polymerize, while heat can not.
DBI is a kind of limpid colorless liquid with low toxicity. As internal-plasticizing agent, it can be used as copolymerizing monomer and also cross-linking agent.
