SBR 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).

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.
