Synthetic rubber

A synthetic rubber is any artificial elastomer. These are mainly polymers synthesised from petroleum byproducts. About 15 billion kilograms (5.3×10¹¹ oz) of rubbers are produced annually, and of that amount two thirds are synthetic. Global revenues generated with synthetic rubbers are likely to rise to approximately US$56 billion in 2020. Synthetic rubber, like natural rubber, has uses in the automotive industry for tires, door and window profiles, hoses, belts, matting, and flooring.

The expanded use of motor vehicles, and particularly motor vehicle tires, starting in the 1890s, created increased demand for rubber. In 1909, a team headed by Fritz Hofmann, working at the Bayer laboratory in Elberfeld, Germany, succeeded in polymerizing methyl isoprene (2,3-dimethyl-1,3-butadiene), the first synthetic rubber.

The first rubber polymer synthesized from butadiene was created in 1910 by the Russian scientist Sergei Vasiljevich Lebedev. This form of synthetic rubber provided the basis for the first large-scale commercial production by the tsarist empire, which occurred during World War I as a result of shortages of natural rubber. This early form of synthetic rubber was again replaced with natural rubber after the war ended, but investigations of synthetic rubber continued. Russian American Ivan Ostromislensky who moved to New York in 1922 did significant early research on synthetic rubber and a couple of monomers in the early 20th century. Political problems that resulted from great fluctuations in the cost of natural rubber led to the enactment of the Stevenson Act in 1921. This act essentially created a cartel which supported rubber prices by regulating production (see OPEC), but insufficient supply, especially due to wartime shortages, also led to a search for alternative forms of synthetic rubber.
