A synthetic rubber is any artificial elastomer. These are mainly polymers synthesised from petroleum byproducts. About 15 billion kilograms 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.
Natural vs. synthetic rubber
Natural rubber, coming from latex of Hevea brasiliensis, is mainly poly-cis-isoprene containing traces of impurities like protein, dirt etc. Although it exhibits many excellent properties in terms of mechanical performance, natural rubber is often inferior to certain synthetic rubbers, especially with respect to its thermal stability and its compatibility with petroleum products.
Synthetic rubber is made by the polymerization of a variety of petroleum-based precursors called monomers. The most prevalent synthetic rubbers are styrene-butadiene rubbers (SBR) derived from the copolymerization of styrene and 1,3-butadiene. Other synthetic rubbers are prepared from isoprene (2-methyl-1,3-butadiene), chloroprene (2-chloro-1,3-butadiene), and isobutylene (methylpropene) with a small percentage of isoprene for cross-linking. These and other monomers can be mixed in various proportions to be copolymerized to produce products with a range of physical, mechanical, and chemical properties. The monomers can be produced pure and the addition of impurities or additives can be controlled by design to give optimal properties. Polymerization of pure monomers can be better controlled to give a desired proportion of cis and transdouble bonds.

Synthetic Rubber (1933)
Introductory intertitle reads: "Down at Deauville they run an open air factory for making india-rubber bodies - ! The material is human."
L/S of several woman doing exercises in the open air. A trainer helps them to stretch their bodies over a wooden bar. "Evidently some ladies don't mind how they treat their figures in the cause of suppleness!" M/S of a trainer forcing a woman's leg up as she stands against a pillar. "This must be a case of the bend justifying the means" - a woman does handstands.
Note: Print shows bad decomposition damage print through - images probably unusable. This is one of the NFTVA prints made from our decomposing nitrate.

Synthetic Rubber And Examples.
Synthetic rubber is any vulcanisable man-made rubber like rubber, which can be stretched to at least twice it's length but it returns to its original shape and dimensions as soon as stretching force is released.
Examples are:-*BUNA-N Rubber/ Nitrile Rubber
*BUNA-S Rubber/ SBR
* Neoprene Rubber
* Butyl Rubber.
