"Synthetic rubber is made through the polymerization of a variety of monomers to produce polymers. These form part of a broad study covered by polymer science and rubber technology. Its scientific name is polyisoprene.
The major commercial source of natural latex used to create rubber is the Para rubber tree, Hevea brasiliensis (Euphorbiaceae). This is largely because it responds to wounding by producing more latex. Henry Wickham gathered thousands of seeds from Brazil in 1876 and they were germinated in Kew Gardens, England. The seedlings were sent to Colombo, Indonesia, Singapore and British Malaya. Malaya was later to become the biggest producer of rubber. Liberia is another source of rubber.
Other plants containing latex include figs (Ficus elastica), euphorbias, and the common dandelion. Although these have not been major sources of rubber, Germany attempted to use such sources during World War II when it was cut off from rubber supplies. These attempts were later supplanted by the development of synthetic rubber."

"In 1879, Bouchardt created one form of synthetic rubber, producing a polymer of isoprene in a laboratory. Scientists in England and Germany developed alternate methods for creating isoprene polymers from 1910-1912.
The first large-scale commercial production occurred in Germany during World War I, as a result of shortages of natural rubber. However, it used a different form of synthetic rubber based on a polymer of butadiene, building on the laboratory work of the Russian scientist Sergei Lebedev. This early form of synthetic rubber was again replaced with natural rubber after the war ended, but investigations of synthetic rubber continued, leading to the 1933 invention which German scientists designated "Buna S". This type of synthetic rubber, a copolymer of butadiene and styrene, still represents about one-half of total world production."

rubber is a naturally occurring substance, it was not invented, it is derived from the sap of rubber treas the same way that maple syrup is in the united states

i might be wrong, but rubber was discovered, not invented.
