Styrene / CAS 100-42-5

The most important uses are the synthetic rubber and plastic monomers for the production of styrene butadiene rubber, polystyrene and foam polystyrene. It is also used for copolymerization with other monomers to produce engineering plastics for a variety of different purposes. For example, ABS resin is prepared by copolymerization with acrylonitrile and butadiene, which is widely used in various household appliances and industry; The San prepared by copolymerization with acrylonitrile is an impact resistant resin with bright color; SBS prepared by copolymerization with butadiene is a thermoplastic rubber, which is widely used as modifier of PVC and polypropylene. In addition, a small amount of styrene is also used as intermediates such as spices. Cinnamyl chloride is obtained by chloromethylation of styrene. It is used as an intermediate of qiantongding, a non narcotic analgesic. Styrene is also used as an easy cough zine for antitussive and expectorant and as an original drug of Weichangning, an anticholinergic drug. It can also be used as a hard monomer for producing styrene acrylic emulsion and solvent type pressure sensitive adhesive, or for cross-linking monomer of unsaturated polyester resin. It is used for organic synthesis and resin synthesis, and for preparing copper plating brightener, which plays the role of leveling and brightening. It is used as a hard monomer for the production of styrene acrylic emulsion and solvent type pressure sensitive adhesive, and it can also be used as cross-linking monomer of unsaturated polyester resin. It is used to make polystyrene, foam polystyrene and styrene butadiene rubber. ABS resin was prepared by copolymerization with acrylonitrile and butadiene; SBS and SIS thermoplastic elastomers were prepared by copolymerization with butadiene and isoprene respectively; Emulsion adhesives and coatings were prepared by copolymerization with vinyl acetate and acrylic ester. It is also used as crosslinking monomer of unsaturated polyester, modification of PVC and polypropylene, and intermediate of synthetic perfume. Cinnamyl chloride is obtained by chloromethylation of styrene. It is used as an intermediate of qiantongding, a non narcotic analgesic. Styrene is also used as the original drug of yikezine, an antitussive and expectorant drug, and Weichangning, an anticholinergic drug. It is used to synthesize styrene butadiene rubber and polystyrene resin, polyester FRP and coatings, synthetic dye intermediate anthraquinone, pesticide emulsifier, medicine, beneficiation agent styrene phosphonic acid, etc. Used for making polystyrene, synthetic rubber, ion exchange resin, etc.
