BASF (Badische Anilin- und Soda-Fabrik) was founded in 1865 in Germany to produce chemicals necessary for soda and acids, but the company expanded its product line and ventured into the area of agricultural products with the purchase of the Haber-Bosch process for producing ammonia. BASF merged with five other companies to form I.G. Farben in 1925.

Bell Laboratories is a company that was created by a merger between Western Electric Research Laboratories and part of the American Telephone & Telegraph (AT&T) company in 1925. Although its primary focus was to design and support equipment used by both merger companies, Bell Laboratories scientists consulted for various companies and the U.S. government, and their research led to such developments as radio astronomy, electron diffraction, and the photovoltaic cell.

The B.F. Goodrich Company, now known as the Goodrich Corporation, was founded in Akron, Ohio, in 1870, and became one of the “big four” rubber companies in the United States. Scientists at Goodrich were very active in the prewar period, creating vinyl in the 1920s and a type of synthetic rubber in the 1930s. The company itself was also active in the prewar period, making various acquisitions of smaller companies.

E. I. du Pont de Nemours and Company was founded in 1802 and began as a gunpowder manufacturer. It developed into one of the largest chemical companies in the world. By World War II, DuPont had established itself as an industrial giant and pioneer in the world of polymer chemistry, having developed neoprene, nylon, and Teflon.

The Dow Chemical Company was founded in 1897 and at first sold only bleach and potassium bromide. The company soon diversified its product line and by the 1930s had become a major producer of products like agricultural chemicals, chlorine, dyestuffs, magnesium metal, and plastic resins. By World War II the company had created several plants dedicated to its magnesium business, which became vital to the war effort.

The Firestone Tire & Rubber Company was founded in 1900 in Akron, Ohio. During World War II, Firestone was one of the “big four” rubber companies.

Fisk Rubber Company was founded in 1899 by Harry George Fisk, his brother Noyes W. Fisk, and partners. Before the war Fisk was very active in rubber research and was one of the top rubber companies in the United States; Fisk was purchased by United States Rubber Company in 1939.

The Goodyear Tire & Rubber Company was founded in 1898 in Akron, Ohio. Originally the company manufactured bicycle tires, but it soon expanded. By World War II, Goodyear, as one of the “big four” rubber companies, had built synthetic-rubber plants in Akron, California, and Texas.

I.G. Farben was founded in 1925. This company was the giant in the German chemical industry conglomerate comprising BASF, Hoechst, and Bayer, and other smaller companies. The conglomerate existed until 1951, when the Allied countries forced its dissolution. Before World War II, I.G. Farben had a partnership with Standard Oil of New Jersey.

JASCO, Inc., or the Joint American Study Company, was created in 1930 as a 50-50 joint venture between I.G. Farben and Standard Oil of New Jersey to develop “borderline processes” in the oil and chemical industries. JASCO work included synthetic-rubber research. In 1939 Standard Oil bought I.G. Farben’s share in JASCO, thus obtaining the patent rights to Buna-S synthetic rubber.

The Royal Dutch/Shell Group founded the American Gasoline Company in 1912, and in 1928 it formed the Shell Development Company to conduct chemical research on gasoline and petroleum by-products. Shell provided butadiene to aid in the synthetic-rubber effort during World War II.

Standard Oil of New Jersey was one of 34 companies created in 1911 by the federal government when it dissolved the Standard Oil Company monopoly. Standard Oil of New Jersey became the largest oil producer in the world and partnered with German industry giant I.G. Farben in the interwar period. During World War II the company was leaned on heavily by the United States for its petroleum-based processes and products.

United States Rubber Company was founded in 1892 and was one of the original 12 stocks in the Dow Jones Industrial Average. By World War II this company had become one of the “big four” rubber companies, with its purchase of the Gillette Safety Tire Company and the success of its plants. In 1961 the company was renamed Uniroyal Inc.

University of Illinois was founded in 1867. The University of Illinois at Urbana-Champaign is the largest in the University of Illinois system. During World War II the University of Illinois, led by Carl Marvel, was one of the main academic research sites of the synthetic-rubber program.



The Baruch Report was the result of the Rubber Survey Committee headed by Bernard Baruch to determine in an unequivocal manner what synthetic rubber should be made from, how much the Unites States needed, and ways to conserve natural rubber.

The Gillette Committee was a subcommittee headed by Iowa “farm-bloc” Senator Guy Gillette to investigate the government’s handling of the synthetic-rubber situation: from stockpiling to contracts to using grain alcohol to create butadiene. Its hearings began in March 1942. While Gillette’s hope that the government would use grain alcohol did not come to fruition, the committee’s findings did prompt governmental action in August 1942, with the appointment of a Rubber Survey Committee.

National Defense Research Committee was a U.S. organization created at the onset of World War II to “coordinate, supervise, and conduct scientific research on the problems underlying the development, production, and use of mechanisms and devices of warfare.” It was superseded in 1941 by the Office of Scientific Research and Development, which was headed by Vannevar Bush, former president of the Massachusetts Institute of Technology. The organization oversaw research, including that on radar and the atomic bomb, and with government funding created various laboratories.

Reconstruction Finance Corporation was an independent government agency created by the Herbert Hoover administration in 1932. The agency gave billions of dollars in aid to state and local governments and made loans to various businesses and banks. During World War II this agency established eight new subsidiary corporations, including the Rubber Reserve Company, and authorized funding to these subsidiaries.

The Rubber Reserve Company (RRC) was a subsidiary of the Reconstruction Finance Corporation headed by Jesse Jones. Between 1940 and 1942 the RRC made little progress in either obtaining rubber or making plans for creating synthetic rubber.

The Rubber Survey Committee was created in 1942 by President Roosevelt and headed by Bernard Baruch to determine details vital to the success of the synthetic-rubber program. Other members included James Bryant Conant, president of Harvard University, and Karl T. Compton, president of the Massachusetts Institute of Technology.

War Production Board (WPB) was created on January 16, 1942, to procure and allocate the materials required for the war effort, including such items as rubber, gasoline, metal, and nylon. The WPB promoted the manufacture of rubber via the butadiene from petroleum process in opposition to the Gillette Committee.



Buna-N Structure

The Bergius process was first developed by Friedrich Bergius in 1913. It converts brown coal (lignite) into crude oil at high temperature and pressure; the process is also known as coal hydrogenation. Before World War II, Bergius sold his patent to BASF, which created several plants dedicated to the process.

Buna-S Structure

Buna-N, nitrile-butadiene rubber, or NBR is a synthetic rubber composed of repeating units of styrene and acrylonitrile monomers. The word Buna is a shortened form of butadiene + Natrium (sodium), which is used in the synthesis. The addition of acrylonitrile decreases the flexibility of the rubber but increases its resistance to oils and greases. NBR does not have one repeating unit; instead there are multiple types of NBR depending on the percentage of acrylonitrile present.

Buna-S, butadiene-styrene rubber, or SBR is a synthetic rubber composed of repeating units of styrene and butadiene monomers. The word Buna is a shortened form of butadiene + Natrium (sodium), which is used in the synthesis. It was initially developed by the Germans. The addition of styrene helps the rubber wear better over time.

Butadiene Structure

Butadiene, or 1,3-butadiene, is a monomer used in the production of many forms of synthetic rubber and other polymers. Butadiene can be manufactured from petroleum or grain alcohol.

Butyl Structure

Butyl is a four-carbon alkyl radical derived from either of the two isomers of butane. Often the use of the word butyl in the context of the World War II Synthetic Rubber Program referred to butyl rubber, a brand of synthetic rubber created by the polymerization of butylenes. Tire inner tubes were the first major use of butyl rubber because of its leakproof qualities.

Carbon black is a material created by incomplete combustion of heavy petroleum products, including various types of tar. A virtually pure elemental carbon in the form of colloidal particles, it is used as a pigment and reinforcement in rubber and other polymers.

Co-polymers are polymers made of more than one type of monomer subunit. Synthetic rubbers like those made from butadiene-styrene and nitrile-butadiene are common examples.

Cold rubber is produced at 41˚F (5˚C), unlike the GR-S rubber produced during World War II at 122˚F (50° C). After the war Carl Marvel and other rubber chemists traveled to Germany in an effort to better understand German rubber advances made in secret during wartime. One of these advances was a cold-rubber process. Later in the United States this process was further refined by combining cold-rubber polymerization and the redox polymerization processes.

Long ton is the standard industrial unit of measurement for rubber. A long ton weighs 2,240 pounds and is approximately 1.12 times as much as a short ton, which is 2,000 pounds. A metric ton (or tonne in the United Kingdom) is 2,205 pounds. Using the word ton can be confusing when the exact measurements are required.

GR-S, or Government Rubber plus Styrene, was the designation for general-purpose synthetic rubber created in World War II by the Americans. The rubber known as Buna-S was selected to become GR-S: butadiene-styrene rubber.

A monomer is a small molecule or atom that binds chemically to other monomers in long chains, which creates a polymer. In the case of synthetic polymers like rubber, this term refers to organic molecules.

Neoprene Structure

Neoprene, or polychloroprene, is a synthetic rubber first produced by DuPont in 1930 under the supervision of Wallace Hume Carothers. Neoprene rubber is resistant to oils and greases.

A polymer can be thought of as a chain that is made up of many links and that can be rigid or pliable. The earliest polymer science involved modifications of naturally occurring polymers. Vulcanization of rubber, invented by Charles Goodyear in the 19th century is the best example of this type of modification.

Redox polymerization is a method of low-temperature polymerization employing oxidation-reduction chemistry and often a hydroperoxide catalyst. This process was developed by the Germans during World War II, although there were Americans working on similar lines of research. The german process was discovered by a team of chemists and rubber-industry representatives headed by Carl Marvel during an investigation of German chemical-industry facilities after the war; when combined with cold-rubber research, the process created a better, more efficient synthetic rubber.

Stearic Acid Structure

Stearic acid is a long-chain fatty acid used in commercial synthetic-rubber syntheses. The addition of stearic acid during the compounding process for natural rubber became common in the 1920s after it was patented in 1921 by W. F. Russell of the Norwalk Tire and Rubber Company.

Styrene Structure

Styrene is a synthetic chemical in the form of a liquid that is derived from petroleum and natural-gas by-products. It is used in the manufacture of many plastics, including rubber; when combined with butadiene, it creates a rubber with good abrasion resistance and good aging stability, and is often blended with natural rubber and widely used in car tires.

Zinc oxide is an inorganic compound with the formula ZnO, which usually appears as a white powder. It is often used as an additive in numerous materials, including rubber. Zinc oxide, along with stearic acid, activates vulcanization and improves thermal conductivity.
