Styrene (C8H8) is an organic compound formed by substituting styrene for a hydrogen atom. The electrons of vinyl group conjugate with benzene ring, insoluble in water, soluble in ethanol and ether, and gradually occur polymerization and oxidation when exposed to air. In industry, it is an important monomer for synthetic resins, ion exchange resins, synthetic rubber and plastics. It is used for the production of styrene butadiene rubber, polystyrene and foam polystyrene. It is also used for copolymerization with other monomers to produce engineering plastics of various uses. For example, ABS resin prepared by copolymerization with acrylonitrile and butadiene is widely used in various household appliances and industries; SAN prepared by copolymerization with acrylonitrile is impact-resistant and glossy resin; SBS prepared by copolymerization with butadiene is a thermoplastic rubber, widely used as modifier of polyvinyl chloride and polypropylene, etc. Styrene is mainly used in the production of styrene series resins and styrene-butadiene rubber. It is also one of the raw materials for the production of ion exchange resins and pharmaceutical products. In addition, styrene can also be used in pharmaceutical, dyestuff, pesticide and mineral processing industries.
