Francis P. Baldwin
Francis Paul Baldwin (November 23, 1915 — August 17, 1993) was a former Exxon Chief Scientist noted for his work on chemical modifications of low functionality elastomers. Personal Baldwin was born on November 23, 1915, in Brooklyn, Kings County, New York, United States. He married Helen Koelbl on Nov. 27, 1943. They lived in Summit, New Jersey, for many years. He died August 17, 1993, in Coupeville, Island County, Washington, US. He went by the nickname 'Baldy'. Education Baldwin received his Bachelor of Science degree in physics from Wagner Memorial Lutheran College in 1941. He received a doctorate from the University of Notre Dame in 1953. Career Baldwin joined Exxon in 1937. Seeking to compatibilize butyl rubber with natural rubber, together with Robert M. Thomas, he found that gaseous chlorination of butyl leads to degradation. This result caused them to switch to a solution-based chlorination process. This process was commercialized in 1960. He supervised t ...

Exxon
ExxonMobil Corporation (commonly shortened to Exxon) is an American multinational oil and gas corporation headquartered in Irving, Texas. It is the largest direct descendant of John D. Rockefeller's Standard Oil, and was formed on November 30, 1999, by the merger of Exxon and Mobil, both of which are used as retail brands, alongside Esso, for fueling stations and downstream products today. The company is vertically integrated across the entire oil and gas industry, and within it is also a chemicals division which produces plastic, synthetic rubber, and other chemical products. ExxonMobil is incorporated in New Jersey. ExxonMobil's earliest corporate ancestor was Vacuum Oil Company, though Standard Oil is its largest ancestor prior to its breakup. The entity today known as ExxonMobil grew out of the Standard Oil Company of New Jersey (or Jersey Standard for short), the corporate entity which effectively controlled all of Standard Oil prior to its breakup. Jersey Standard g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butyl Rubber
Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C4H8)n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based. Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene. Structurally, polyisobutylene resembles polypropylene, but has two methyl groups substituted on every other carbon atom, rather than one. Polyisobutylene is a colorless to light yellow viscoelastic material. It is generally odorless and tasteless, though it may exhibit a slight characteristic odor. Properties Butyl rubber has excellent impermeability to gas diffusion, and the long polyisobutylene segments of its polymer chains give it good flex properties. The formula for PIB is: –(–CH2–C(CH3)2–)n– The formula for IIR is: It can be made from the mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer Scientists And Engineers
A polymer (; Greek '' poly-'', "many" + ''-mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word πολύς (''polus'', meaning "many, much") and μέρος (''meros'', meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Summit, New Jersey
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of pe ...

Ethylene Propylene Rubber
Ethylene propylene rubber (EPR, sometimes called EPM referring to an ASTM standard) is a type of synthetic elastomer that is closely related to EPDM rubber. Since introduction in the 1960s, annual production has increased to 870,000 metric tons. http://www.azom.com/article.aspx?ArticleID=1822 ''Azom.com'', ''Ethylene Propylene Rubbers'', Thursday 19 April 2012http://www.iisrp.com/webpolymers/10epdmsep11.pdf ''iisrp'', ''Ethylene-Propylene Rubbers & Elastomers'', Thursday 19 April 2012 EPR is used in electrical cable insulation, and in many flexible rubber goods such as hoses or weatherstripping. Properties EPM is considered a valuable elastomer due to its useful chemical and physical properties; it is resistant to heat, oxidation, ozone and the weather (owing to its stable, saturated backbone) and it is also not susceptible to color loss. As a non-polar compound, EPM is an electrical resistor and it is insoluble in many polar solvents, both protic and aprotic. Amorphous forms ...
