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. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.
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.
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.
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.
It is a colorless liquid that is typically stored with a stabilizer to suppress polymerization. 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 ...
An important application of 2-vinylpyridine involves the production of a latex terpolymer of 2-vinylpyridine, styrene, and butadiene, for use as a tire-cord binder. The tire cord is treated first with a resorcinol-formaldehyde polymer and then with a terpolymer made from 15% 2-vinylpyridine, styrene, and butadiene. This treatment gives the ...

Polystyrene is a synthetic hydrocarbon polymer that is widely adaptive and can be used for a variety of purposes in drug delivery. These methods include polystyrene microspheres, nanoparticles, and solid foams. In the biomedical engineering field, these methods assist researchers in drug delivery, diagnostics, and imaging strategies. [1] [2]
