Around 80% of styrene is produced by the dehydrogenation of ethylbenzene. This is achieved using superheated steam (up to 600 °C) over an iron(III) oxide catalyst. [21] The reaction is highly endothermic and reversible, with a typical yield of 88–94%. The crude ethylbenzene/styrene product is then purified by distillation.
Trinseo's precursor Styron was formed in August 2009 when Dow Chemical Company combined several of its businesses--styrenics; polycarbonate and compounds & blends; Dow Automotive plastics; emulsion polymers (paper and carpet latex); and synthetic rubber — as part of a larger process of identifying and selling non-strategic assets.
Acrylonitrile butadiene styrene (ABS) is a thermoplastic resin, used primarily in colored products that need to be heat and impact-resistant, such as vacuum cleaners or power tools. It is also commonly found in vehicles, mobile phone housings and recreational goods.
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 ...
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 ...
About 50% of car tires are made from various types of SBR. The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. [3] SBR is not to be confused with the thermoplastic elastomer, styrene-butadiene block copolymer, although being derived from the same monomers.
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.
In combination with styrene, vinylbenzyl chloride is used as a comonomer in the production of chloromethylated polystyrene. [1] It is produced by the chlorination of vinyltoluene . Often vinyltoluene consists of a mixture of 3- and 4-vinyl isomers, in which case the vinylbenzyl chloride will also be produced as a mixture of isomers.
