Styrene-Monomer

What is a monomer?

First we need to know what a monomer is. what a Styrene Monomer ? The word monomer is derived from the Greek entry of mono by the meaning “one” and meros by the meaning of “part”. A monomer is a type of molecule that forms the main unit of polymers. Monomers bind to other Types monomers through the process of various reactions, usually through catalysts known as polymerization, to form molecules with repetitive chains;

In which two separate molecules are joined together by pairs of electrons to form covalent bonds. In nature, natural monomers bind to each other to from larger molecules, such as glucose, glycogen, and cellulose.

In the industries along with synthetic process, styrene, isoprene, propylene and vinyl chloride are some examples of monomers used in polymer science and industry. In this article, we will explain styrene monomer.

Styrene monomer

Styrene is an organic compound with the chemical formula C8H8, which is industrially produced from the dehydrogenation of ethylbenzene and has a strong affinity for the polymerization process. Styrene monomer is a colorless liquid with an odor similar to aromatic materials with a melting point of 30 degrees and a boiling point of 146 degrees Celsius and is flammable.

Even its steam, because of the heavy air of the thrust, can travel long distances in the environment, and styrene can explode as it approaches a source of heat and fire. Water spray, CO2 powder or foam can be used to extinguish it, and due to its negative effect on the respiratory system and the human eye, goggles and masks should be used during firefighting operations.

History of styrene monomer

Styrene is naturally found in small amounts in some plants and foods (cinnamon, coffee beans, honeysuckle and peanut trees, and a sweet American tree) and is also found in coal tar, which was discovered in 1839 by a German named Edward Simon, who was able to extract a resin-volatile liquid from the American sweet tree (Liquidambar Styraciflua), called it “styrole” or styrene.

He also found that when styrene was exposed to air, light, or heat, it gradually turned into a hard, rubbery substance that he called Meta styrene, or “styrene oxide.” In later years, the German chemist Auguste Hoffmann and his student John Blyth developed the experimental formula for the styrene monomer C 8 H 8.

Styrene monomer polymerization and its applications in industry

The vast majority of ethylbenzene produced in the world is for the production of styrene, and styrene is used in the production of polystyrene monomers. Also some products such as: polystyrene, ABS, styrene-butadiene rubber, latex styrene-butadiene, styrene-isoprene-styrene, styrene-ethylene / butylene-styrene, styrene-divinyl benzene, acrylonitrile styrene resin and non-ferrous polyesters are included of styrene.

These materials are used in rubber, plastics, insulation, fiberglass, pipes, car and boat parts, food containers and carpet slats, refrigeration insulation in refrigerators and freezers, sports equipment, etc.
