Robert Banks (chemist)
Robert L. Banks (November 24, 1921 – January 3, 1989) was an American chemist. He was born and grew up in Piedmont, Missouri. He attended the University of Missouri - Rolla, and initiated into Alpha Phi Omega in 1940. He joined the Phillips Petroleum company in 1946 and worked there until he retired in 1985. He died in Missouri on January 3, 1989. Technical contributions He was a fellow research chemist of J. Paul Hogan. They began working together in 1946, and in 1951 invented "crystalline polypropylene" and high-density polyethylene (HDPE). These plastics were initially known by the name Marlex. The polymerization of ethylene was made possible by their discovery of the so-called Phillips catalyst. Recognition In 1987, Banks and Hogan won the Perkin Medal, and in 2001 they were inducted into the National Inventors Hall of Fame. Both were given a '' Heroes of Chemistry'' award by the American Chemical Society in 1989. Dr. Banks was inducted into the Plastics Hall of Fame ...

Piedmont, Missouri
Piedmont is a city in northwestern Wayne County in Southeast Missouri, United States. Its population was 1,897 at the 2020 census. Part of the Ozark Foothills Region, it is at the convergence of State Highways 34 and 49. Piedmont, transliterated as "foot of the mountain," is named for its position at the foot of Clark Mountain, a 1424-foot summit approximately two miles north of the town. History Piedmont was platted in 1871 when the Iron Mountain Railroad was extended south to that point. The community derives its name from the French ''pied'' and ''mont'', meaning "foot" and "mountain" respectively. A post office called Piedmont has been in operation since 1872.

Phillips Catalyst
The Phillips catalyst, or the Phillips supported chromium catalyst, is the catalyst used to produce approximately half of the world's polyethylene. A heterogeneous catalyst, it consists of a chromium oxide supported on silica gel. Polyethylene, the most abundant synthetic polymer, is produced industrially by the polymerization of ethylene: :n C2H4 → (C2H4)n Although exergonic (i.e., thermodynamically favorable), the reaction requires catalysts. Three main catalysts are employed commercially: the Phillips catalyst, Ziegler–Natta catalysts (based on titanium trichloride), and, for specialty polymers, metallocene-based catalysts. Preparation and mechanism of action The Phillips catalyst is prepared by impregnating high surface area silica gel with chromium trioxide or related chromium compounds. The solid precatalyst is then calcined in air to give the active catalyst. Only a fraction of the chromium is catalytically active, a fact that interferes with elucidation of the ...

Polymer Scientists And Engineers
A polymer (; Greek ''wikt:poly-, poly-'', "many" + ''wikt:-mer, -mer'', "part") is a Chemical substance, substance or material consisting of very large molecules called macromolecules, composed of many Repeat unit, 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 compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form glass, amorphous and crystallization of polymers, semicrystalline structures rather ...

Plastics Hall Of Fame
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

Marlex
Marlex is a trademarked name for crystalline polypropylene and high-density polyethylene (HDPE). These plastics were invented by J. Paul Hogan and Robert Banks, two research chemists at the Phillips Petroleum Company. Interest in the material in the 1950s arose from its high melting point and tensile strength, making it more desirable than the more common form of polyethylene. For example, the medical community in 1958 was eager to use Marlex 50 crystalline polyethylene which softens at . Objects made of Marlex could be sterilized in high-temperature autoclaves without affecting their form. Marlex was used by Wham-O for their Hula Hoops in the 1950s, which helped create a market for this form of plastic. It is now used surgically as a reinforcing mesh in inguinal hernia repair Inguinal hernia surgery is an operation to repair a weakness in the abdominal wall that abnormally allows abdominal contents to slip into a narrow tube called the inguinal canal in the groin region.
