Styrene Monomer

Styrene, also known as vinyl benzene, is an organic compound with the chemical formula C6H5CH=CH2. This cyclic hydrocarbon is a colorless oily liquid that evaporates easily and has a sweet smell, although high concentrations confer a less pleasant odor. Styrene is the precursor to polystyrene and several copolymers. Approximately 15 billion pounds are produced annually.
