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.
Blood type (also called a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
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.

Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
Ineos Group Limited is a British multinational conglomerate headquartered and registered in London. As of 2021, [update] 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.
If styrene-butane co-polymer has a high butylene content, styrene-butadiene rubber (SBR) is formed. The impact strength of styrene-butadiene co-polymers is based on phase separation, polystyrene and poly-butane are not soluble in each other (see Flory–Huggins solution theory). Co-polymerization creates a boundary layer without complete mixing.
