How to detect Styrene
Formula: C8H8 | CAS: 100-42-5
Synonyms: ethenylbenzene, ethenyl benzene, phenylethylene, styrene monomer, styrol, vinyl benzene
Styrene is chiefly used in the manufacture of polystyrene, with large quantities used in copolymerisation with for example butadiene and acrylonitrile, to form a number of plastic and rubber materials.
