Styrene, also known as ethenylbenzene, vinylbenzene, and phenylethene, is an organic compound, chemical formula is C8H8, vinyl electrons and benzene conjugated ring, insoluble in water, soluble in ethanol, ether and other organic solvents, is an important monomer of synthetic resin, ion exchange resin and synthetic rubber.
Application of Styrene
Styrene is an important monomer of synthetic rubber, adhesives and plastics. [3,4,5] It is used for the synthesis of styrene butadiene rubber and polystyrene resin, polyester glass fiber reinforced plastics and coatings. It is used for preparing polystyrene, ion exchange resin, and foam polystyrene. It is also used for copolymerization with other monomers to produce various engineering plastics, such as copolymerization of acrylonitrile and butadiene to produce ABS resin, widely used in various household appliances and industries. Copolymerization with acrylonitrile, obtained SAN is a resin with shock resistance and bright color. The SBS produced by copolymerization with butadiene is a thermoplastic rubber, which is widely used as a polyvinyl chloride and acrylic modifier. SBS and SIS thermoplastic elastomers are made with butadiene and isoprene copolymerization, and as a crosslinking monomer, styrene is used in the modification of PVC, polypropylene, and unsaturated polyester.
