What is polystyrene reaction?
Polystyrene is an addition polymer that results when styrene monomers interconnect (polymerization). In the polymerization, the carbon-carbon π bond of the vinyl group is broken and a new carbon-carbon σ bond is formed, attaching to the carbon of another styrene monomer to the chain.
Does styrene react with water?
Styrene is primarily a synthetic chemical. It is also known as vinylbenzene, ethenylbenzene, cinnamene, or phenylethylene. It often contains other chemicals that give it a sharp, unpleasant smell. It dissolves in some liquids but doesn’t dissolve easily in water.
What is the chemical reaction for the production of polystyrene?
Polystyrene is produced in an addition polymerisation reaction from styrene monomers. The reaction is highly exothermic, the heat of reaction for the polymerisation is -121 kJ mol-1 (at 25oC).
What is the chemical formula of styrene?
C8H8
Styrene/Formula
What is styrene plastic?
Styrene is a special type of thermoplastic commonly used to build displays, signage, and other fixtures we see on a day-to-day basis. With such exceptional dimensional stability and strength, styrene plastic is the obvious choice for machining a wide variety of prototypes and models.

Is styrene a plastic?
Is styrene a gas or liquid?
Styrene is a colourless liquid which is used for the production of plastic pipes, fibreglass, electrical wiring and resins. Styrene can enter the environment after being released by the manufacturer in the form of a gas or liquid.
How does styrene become polystyrene?
The Basics: When styrene molecules are linked together into a polymer, polystyrene is created. Polystyrene is an inert plastic that can be used to make many products, such as disposable plates, cups and other foodservice packaging products.
What is styrene made from?
Almost all styrene is now produced by dehydrogenation of ethylbenzene, a compound obtained by reacting ethylene and benzene—both of which in turn are derived from petroleum. More than half of the styrene produced is made into polystyrene, a light, stiff plastic widely used in injection-molded or foamed articles.
Why is styrene used?
Styrene is a chemical used to make latex, synthetic rubber, and polystyrene resins. These resins are used to make plastic packaging, disposable cups and containers, insulation, and other products. Styrene is also produced naturally in some plants. People may be exposed to styrene by breathing it in the air.
What are the health effects of styrene?
Health effects. Styrene is regarded as a “known carcinogen”, especially in case of eye contact, but also in case of skin contact, of ingestion and of inhalation, according to several sources. Styrene is largely metabolized into styrene oxide in humans, resulting from oxidation by cytochrome P450.
How is styrene monomer made?
How It’s Made. Styrene is one of the most important monomers produced by the chemical industry today. Styrene monomer is a basic building block of the plastics industry. The conventional method of producing styrene involves the alkylation of benzene with ethylene to produce ethylbenzene, followed by dehydrogenation of ethylbenzene to styrene.
What is the chemical formula for styrene?
Styrene. The chemical formula for styrene is C 8 H 8, but its structural formula, CH 2 =CHC 6 H 5, more clearly reveals the sources of its commercially useful properties. Styrene is a member of a group of chemical compounds broadly categorized as vinyls —organic compounds whose molecules contain a double bond between two carbon atoms.
How is stystyrene metabolized in humans?
Styrene is largely metabolized into styrene oxide in humans, resulting from oxidation by cytochrome P450. Styrene oxide is considered toxic, mutagenic, and possibly carcinogenic. Styrene oxide is subsequently hydrolyzed in vivo to styrene glycol by the enzyme epoxide hydrolase.
