styrene
sty·rene S0831500 (stī′rēn′)n. A colorless oily liquid, C8H8, having a penetrating odor; the monomer for polystyrene.
[Latin styrax, storax; see storax + -ene.]styrene (ˈstaɪriːn) n (Elements & Compounds) a colourless oily volatile flammable water-insoluble liquid made from ethylene and benzene. It is an unsaturated compound and readily polymerizes: used in making synthetic plastics and rubbers. Formula: C6H5CH:CH2. See also polystyrene[C20: from styr(ax) + -ene]sty•rene (ˈstaɪ rin, ˈstɪər in)
n. a colorless, water-insoluble liquid, C8H8, that copolymerizes with other materials to form synthetic rubbers.

TranslationsStyrene
styrene[′stī‚rēn] (organic chemistry) C6H5CH:CH2 A colorless, toxic liquid with a strong aroma; insoluble in water, soluble in alcohol and ether; polymerizes rapidly, can become explosive; boils at 145°C; used to make polymers and copolymers, polystyrene plastics, and rubbers. Also known as phenylethylene; styrene monomer; vinylbenzene. Styrene (also phenylethylene, vinylbenzene), a colorless liquid with a characteristic odor, a melting point of 30.6°C, a boiling point of 145.2°C, and a density of 0.906 g/cm3 (20°C). 
Styrene is practically insoluble in water but is miscible with most organic solvents. The compound is readily oxidized, it combines with halogens, and it also undergoes polymerization and copo-lymerization with various monomers. Since polymerization proceeds at room temperature, and sometimes explosively, inhibitors (tert-butylpyrocatechol, hydroquinone) are added during storage. The principal method of producing styrene is the catalytic dehydrogenation of ethylbenzene in a steam flow at 500°–630°C. Styrene is used chiefly in the production of polystyrene, as well as in the production of such copolymers as butadiene-styrene rubbers and polyester resins. Copolymers of styrene with divinyl-benzene serve as ion-exchange resins. Vapors of styrene irritate the mucous membrane; concentration in the air must not exceed 0.005 milligram per cubic decimeter. styrene
sty·rene (stī'rēn), Phenylethylene; the monomer from which polystyrenes, plastics, and synthetic rubber are made; together with divinylbenzene (for cross-linking), it is the basis of many synthetic ion exchangers.
