Product Description

Product Description

Styrene is a certain organic chemical compound having the chemical formula C8H8 and structural formula CH2=CHC6H5, also known as styrol, vinylbenzene, phenylethene,phenylethylene,styrene,styreen and so on. Its chemical structure is made up of a benzene ring bonded onto a vinyl group . At room temperature and pressure, styrene is a clear, colorless liquid. Styrene is an important monomer of synthetic rubber, adhesives and plastics, such as styrene sheet. Styrene is a common vinyl monomer and is the raw material for the synthesis of polystyrene. In addition to bulk polymers, copolymers can be copolymerized with other monomers, such as acrylates and acrylonitrile. It can be polymerized under free radical photoinitiator or thermal initiator, and can also autopolymerize at high temperature. As vinyl monomer, its polymerization reaction activity is lower than acrylate, methacrylate and other high activity monomer, higher than vinyl acetate and other low activity monomer. In addition, styrene can also be used as a monomer for anionic polymerization, cationic polymerization and coordination polymerization.

Uses

 

Styrene is an important monomer of synthetic rubber, adhesives and plastics. 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.
Syrene is used as a hard monomer for the production of styrene acrylic emulsion and solvent pressure sensitive adhesive. Emulsion adhesive and paint can be prepared by copolymerization with vinyl acetate and acrylic ester. Styrene is one of the most commonly used vinyl monomers in the scientific field, used in various modified and composite materials.
In addition, a small amount of styrene is also used as perfume and other intermediates. By chloromethylation of styrene, cinnamyl chloride is used as an intermediate for the non anesthetic analgesic strong pain determination, and styrene is also used as an antitussive, expectorant and anticholinergic original medicine in stomach Changning. It can be used to synthesize anthraquinones dye intermediates , pesticide emulsifiers, and styrene phosphonic acids ore dressing agent and copper plating brighteners.
