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.
