Styrene, which gives off a penetrating sweetish odour, is therefore one of the aromatic hydrocarbons. In the early 19th century, styrene was first isolated from storax, an aromatic balsam obtained from the flowering shrub Styrax officinalis, after which the compound is named. The liquid, known as styrol, was first polymerized to a solid form, later called metastyrol, in 1839.
