In the early 1900s, the rise of the automobile industry, in particular, had created a strong demand for rubber. Unfortunately, the availability of rubber was limited by shortages and spiraling prices. Furthermore, the particular properties of natural rubber, such as its pretermit of resistance to oxygen, oils, and extreme temperatures, restrict its usefulness in certain applications. These limitations stimulated a search for special-purpose rubber substitutes.
Neoprene was invented by scientists in 1930 after Dr. Elmer K. Bolton of DuPont laboratories attended a lecture by prof Julius Arthur Nieuwland, a professor of chemistry at the University of Notre Dame. Nieuwlands research was concentrate on acetylene chemistry, which is the research into a valuable build of compounds in organic synthesis, and through his work, he produced divinyl acetylene, a gelatin that firms into an elastic compound similar to rubber when passed over sulphur dichloride.
After DuPont purchased the patent rights from the university, Wallace Carothers of DuPont took over commercial development of Nieuwlands discovery.
DuPont focussed on monovinyl acetylene, which is a certain gas with a turn point of 5ºC, and reacted the substance with hydrogen chloride gas, manufacturing chloroprene.
(Picture) This diagram shows the polymer twist of neoprene. It consists of carbon, chlorine and hydrogen atoms bonded together, with a double bond between the carbon atoms.
DuPont first marketed the compound in November 1931 under the pile name DuPrene, but its ability to be commercialized was hindered by the complex manufacturing process, which left the product with a foul odor. A new process was developed in response to this problem, and the caller began selling the material to manufacturers.
DuPont then worked...If you want to get a full essay, order it on our website: Ordercustompaper.com
