Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2.Its structure consists of a vinyl group as substituent on benzene.Styrene is a colorless, oily liquid, although aged samples can appear yellowish.
Styrene monomer (SM) is an intermediate product. It is a colorless liquid that polymerizes easily. Polystyrene (PS) is a thermoplastic resin that is used in many applications, such as disposable packaging, electronic devices, large appliances (for example in refrigeration liners) and household goods.
The major uses of styrene include making plastics, synthetic rubbers and latex paints, according to this report posted at the National Library of Medicine web site. It's manufactured into a range ...
Based on 2002–2003 data, the Freeport plants produced 27 billion lbs of product – or 21% of Dow's global production. [21] [better source needed] In 1942, Dow began its foreign expansion with the formation of Dow Chemical of Canada in Sarnia, Ontario, to produce styrene for use in styrene-butadiene synthetic rubber.

Styrene, for example, is distilled at temperatures above 100 °C whereupon it undergoes thermal polymerisation at a rate of ~2% per hour. [1] This polymerisation is undesirable, as it can foul the fractionating tower ; it is also typically exothermic , which can lead to a runaway reaction and potential explosion if left unchecked.
Ineos Group Limited is a British multinational conglomerate headquartered and registered in London. As of 2021, it was the fourth largest chemical company in the world, with additional operations in fuel, packaging and food, construction, automotive, pharmaceuticals, textiles, and professional sports.
In August 2005, styrene began leaking from a rail car in Cincinnati's East End. That was not the result of a derailment, but the leak forced evacuations and shelter-in-place orders for residents.
Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the ...
