Description

Styrene Butadiene Rubber is derived from two monomers, styrene and butadiene. The mixture of these two monomers is polymerized by two processes: from solution (S-SBR) or as an emulsion (E-SBR).

History

Styrene Butadiene Rubber was created during World Wars I and II. Around World War I, a polymer was created. This was called BuNa, as an abbreviation of Butadiene, one of the monomers, and Sodium, a catalyst. Soon after BuNa was discovered, scientists created a new polymer made out of Butadiene and Styrene. This was called BuNa-S. This polymer was invented by the Germans and improved upon by the Americans. It was soon renamed to SBR, and is now one of the most important synthetic rubbers, finding applications in a majority of industries around the world.


Synthesis

Styrene Butadiene Rubber is a polymer made of two monomers, namely [Styrene] and [Butadiene]. Styrene, or ethenylbenzene, is an organic compound used in a variety of synthesis. It is commercially formed from ethylbenzene hydroperoxide, toluene, or benzene. Butadiene, or 1,3-Butadiene, is an organic monomer used in the synthesis of rubbers. It is commercially formed from [dehydrogenation] of n-Butane, or from ethanol.

Styrene Butadiene Rubber can be formed from Styrene and Butadiene from both ionization and free radical polymerization. Ionization polymerization is called 'Solution polymerization' and free radical polymerization is called 'Emulsion polymerization'.

Uses

Styrene Butadiene Rubber is a abrasion resistant replacement for natural rubber, having very similar properties. One of it's major uses is in the manufacturing of automobile and truck tires. It is sometimes produced in latex form to be used as a rubbery adhesive. Some other uses include belts, floors, wire and cable insulation, and footwear. Additionally, it is also sometimes used as an alternative to PVA (PolyVinyl Acetate).
