Polystyrene is a polymer made from the monomer styrene, a liquid hydrocarbon that is commercially manufactured from petroleum. At room temperature, polystyrene is normally a solid thermoplastic, but can be melted at higher temperature for molding or extrusion, then resolidified. Styrene is an aromatic monomer, and polystyrene is an aromatic polymer.

Polystyrene was first manufactured in 1839 by Eduard Simon, a German apothecary. While Eduard isolated the substance from natural resin, he did not realize what he had discovered. It took another German, organic chemist, Hermann Staudinger, to realize that Simon's discovery contained long chains of styrene molecules, which was a plastic polymer. Pure solid polystyrene is a colorless, harder plastic with limited flexibility which can be cast into molds with fine detail. Polystyrene can be transparent or can be made to take on various colors. It is economical and is used for producing plastic model assembly kits, plastic cutlery, CD "jewel" cases, and many other objects where a fairly rigid, economical plastic of any of various colors is desired.
