Human: Any artificial elastomer used as synthetic rubber primarily originates from petroleum byproducts, mainly polymers. Worldwide production generates approximately thirty-three billion pounds or fifteen billion kilograms annually, out of which two thirds comprise synthetic materials. Estimated revenues in 2020 should reach about US$56 billion globally. The extensive application in the automotive industry for manufacturing tires, hoses, matting, belts, and flooring uses synthetic rubber like its natural counterpart.\nThe accelerated expansion of bicycle usage from around the 1890s with increased focus on pneumatic tire applications, created growing demand for synthetic rubbers, such as styrene-butadiene rubber derived by polymerizing isoprene at high temperatures in Germany during the year 1909 under Bayer Laboratory headed by Fritz Hofmann. In the early part of that century (in Russia), a researcher, Sergei Vasiljevich Lebedev synthesised synthetic rubber first time by producing polymer from butadiene by creating Russian monomer based rubbers.\nWorld War I accelerated large-scale industrial production due to the shortages in natural supplies but natural substitutes again were back at places during peacetime period in countries worldwide. An early prominent researcher, Sergei Lebedev continued studies, and some researchers worked abroad in the USA with help from scientists there, which gave good initial impetus for future developments in producing more affordable artificial rubber.\nThe rapid inflation due to large increase in demand, along with global political uncertainties of late 1920s made natural sources difficult leading eventually the U.S Congress implementing an anti trust measure named the Stevenson Act, thereby restricting market operations which allowed the formation of international cooperation by oil producers across countries worldwide at time when all other available natural sources fell into crises.\nIn the early decades, especially around twenties, large number companies turned to producing synthetic rubber mainly due the rise in prices because they could reduce supply short falls resulting during wartime. At the same point research continued with an attempt made from some institutions located inside America for creating synthetic products derived based upon chemical and non petroleum monomers not present originally within old European methods so applied at laboratory conditions under researchers like Fr Julius Nieuwland from United states University of Notre Dame. This work ultimately gave the discovery which could finally be put into mass production that in fact turned out neoprene. Later a lot breakthrough came up with American based DuPont who began successful application of producing products for industrial usages as fuel hose or other mechanical components.\nThe establishment (at Moscow under Joseph Stalin's five-year first plan initiated from year) on the basis (July7, 1932 in Yaroslavl region ) SK-1 (SK from synthetic Russian: Kauchuk).In year twenty three German Chemists created their new product and trademarked it ' Buna'. They discovered first polymer chain derived as by combining ethylene dichloride or butadiene . As time advanced, the introduction of many chemical materials made a long history so many different types got developed alongwith several variants.\nThe major reason to replace old method in production is because the use in car and aircraft for tyres increased with great deal leading companies across countries to invest billions each on setting up huge rubber factory complex with highly trained workforce and best technologies making mass production very affordable .Natural sources also did experience scarcity with all world events from world wars onwards impacting badly natural production of rubber that is used to replace old natural type and give alternative for synthetic manufacturing purposes especially the tires etc for vehicles.\nAll these studies indicate clearly as one reads, on its usage across wide varieties ranging automobile applications ( like doors , profiles) along many industries (flooring material too in various form suchas insulations also.) of products. This gives us a brief idea about use across all other countries including US and Canada -in particular to see their performance over longer duration so this could explain why natural sources had a hard time as supply went short falling badly .The most synthetic types have very few chemicals as mentioned here: butadiene (which can make different polymers like polystyrene too , or also neoprene derived using same two.) is well known rubber with good quality as one has more properties as mechanical durability which it never did natural ones when exposed long time due its nature so that this artificial method gave higher level stability thermal stability to be resistant oils gasoline heat all.
