Synthetic rubber, like other polymers, is made from various petroleum-based monomers. Some synthetic rubbers are less sensitive to ozone cracking than natural rubber. Natural rubber is sensitive owing to the double bonds in its chain structure, but some synthetic rubbers do not possess these bonds and so are more resistant to ozone cracking.
Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist [1] [2] and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.
Fritz Hofmann (Friedrich Carl Albert) (2 November 1866 in Kölleda – 22 October 1956 in Hanover) was a German organic chemist who first synthesized synthetic rubber. Hofmann studied chemistry in Rostock. [1] On September 12, 1909, he filed a patent for the manufacture of the world's first synthetic rubber. [2]
Mesoamericans used natural rubber for balls, and figurines. [1] ... the first fully synthetic thermoset, ... and cup, was invented by Dow Chemical. [1] 1957:
In April 1930, one of Carothers' staff, Dr. Arnold M. Collins, isolated chloroprene, a liquid which polymerized to produce a solid material that resembled rubber. This product was the first synthetic rubber and is known today as Neoprene. [18] [19]
The first synthetic polymer was invented in 1869 by John Wesley Hyatt. He created a substitute for ivory from elephant tusks, which was being used at the time to make billiard balls.
Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. [1] Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals.
Wallace Carothers invented the first synthetic rubber called neoprene in 1931, the first polyester, and went on to invent nylon, a true silk replacement, in 1935. Paul Flory was awarded the Nobel Prize in Chemistry in 1974 for his work on polymer random coil configurations in solution in the 1950s.
