The story of the word

Styrene was first distilled in 1839 from storax, the sweet resin tapped from the oriental sweetgum tree and burned as incense since antiquity. Chemists kept the plant's Greek name after the plant became irrelevant to the process, so a petrochemical still carries the label of a temple perfume. Commercial polystyrene arrived in the 1930s; the foam version came a decade or so later.
