What is Polystyrene ((C8H8)n)?
(C8H8)n is a synthetic aromatic hydrocarbon polymer with chemical name Polystyrene. It is a hard, brilliantly transparent, stiff resin. It is produced by the polymerization of styrene and is the most widely used plastic. At room temperature, the thermoplastic polymer is a solid but when heated above 100 °C it flows. It becomes rigid again when it cools down. Polystyrene is insoluble in water. This compound is non-biodegradable with a couple of exceptions. It is easily dissolved by many aromatic hydrocarbon solvents and chlorinated solvents. It is widely used in the food-service industry as rigid trays, containers, disposable eating plates, bowls, etc.
