Use

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.
