Metystyreenit

Metystyreenit is a term used in some contexts, particularly in older or specialized chemical literature, to refer to styrene or its derivatives. The "met" prefix can sometimes be an archaic or less common way to indicate a methyl group or a related structural modification, though in the case of styrene, it's generally understood to refer to the parent compound itself. Styrene, also known as vinylbenzene, is an organic compound with the chemical formula C8H8. It is an aromatic hydrocarbon with a vinyl group attached.

Styrene is a colorless, oily liquid with a sweet, pungent odor at low concentrations, though it becomes unpleasant at higher levels. It is a volatile organic compound and is flammable. Industrially, styrene is produced primarily by the dehydrogenation of ethylbenzene. Its main use is as a monomer, a building block for polymers. The most well-known polymer derived from styrene is polystyrene.

Polystyrene is a widely used plastic found in many everyday items, including disposable cutlery, CD cases, and Styrofoam (expanded polystyrene). Styrene is also a component in the production of other copolymers, such as styrene-butadiene rubber (SBR), used in tires, and acrylonitrile butadiene styrene (ABS), a tough, impact-resistant plastic. The industrial importance of styrene has made it a significant commodity chemical.
