Polybutadiene was one of the first elastomers or rubbers to be invented. Polybutadiene was first polymerized in 1910 by a Russian scientist named Sergei Vasilyevich. Slowly According to this discovery, the Soviet Union was the first country to succeed in the industrial production of this polymer in the late 1930 s.
Germany and the United States were among the countries that contributed a lot to the research and development of polybutadiene production. After World War II in the mid-1950s, major advances in catalysts, especially the production of Ziegler Nata catalysts, led to the production of new and improved types of most polymers, including polybutadiene. Figure (1) shows the butadiene monomer which, as shown in this figure, has two carbon-carbon double bond bonds. LBPC Butadiene rubbers, produced by the solution polymerization process, have a very high elasticity and degree of resistance to dynamic stress and retain these properties even at extremely low temperature.

Styrene butadiene rubber is widely used in various industries and as ordinary rubber. This material is a cheap elastomer that is used for general purposes and in some cases replaces rubber. The reason for the success of this type of composite rubber is its various properties and many applications. Also, this material is the only example that has long-term elasticity and can meet many needs of new technology.
