Henry Hsieh (astronomer)
Henry L. Hsieh was a Phillips Petroleum scientist known for contributions to polymerization chemistry, specifically anionic polymerization. Education Hsieh was a native of Shanghai, China. He received his BS Chemistry at the University of Akron in 1954. He then went to Princeton, where he earned a MA in Chemistry in 1956, and a PhD in 1957 in Organic / Polymer chemistry. Career After completing his doctoral work, he joined Phillips in 1957 as a research chemist in their rubber synthesis branch. He became an authority on polymerization chemistry, holding 135 patents and publishing more than 50 scientific articles. He was responsible for the development of Solprene synthetic rubbers, K-Resin plastic, Butarez CTL solid rocket fuel binder and Phil-ad VIII multi-grade motor oil additive. In 1974, future Goodyear Medal winner Roderic Quirk worked in Hsieh's anionic polymerization lab. Hsieh's most cited journal article is a review on the kinetics of alkyllithium initiated polym ...

Phillips Petroleum
Phillips Petroleum Company was an American oil company incorporated in 1917 that expanded into petroleum refining, marketing and transportation, natural gas gathering and the chemicals sectors. It was Phillips Petroleum that first found oil in the North Sea on December 23, 1969, at a position that was later named Ekofisk. On August 30, 2002, Conoco Inc. merged with Phillips Petroleum to form ConocoPhillips, becoming the third largest integrated energy company and second-largest refining company in the United States. The company moved its headquarters to Houston.Christopher J. Castaneda,"Phillips Petroleum Company." ''Encyclopedia of Oklahoma History and Culture''.Accessed 04 February 2013. In 2012, ConocoPhillips split into two separate companies. The legacy company kept its name, and spun off the midstream and downstream portions of its business. The new company, which owns the refinery, chemical and pipeline assets formerly held in ConocoPhillips, is named Phillips 66, the bra ...

Anionic Polymerization
In polymer chemistry, anionic addition polymerization is a form of chain-growth polymerization or addition polymerization that involves the polymerization of monomers initiated with anions. The type of reaction has many manifestations, but traditionally vinyl monomers are used.Hsieh, H.;Quirk, R. ''Anionic Polymerization: Principles and practical applications''; Marcel Dekker, Inc.: New York, 1996.Quirk, R. Anionic Polymerization. In ''Encyclopedia of Polymer Science and Technology''; John Wiley and Sons: New York, 2003. Often anionic polymerization involves living polymerizations, which allows control of structure and composition. History As early as 1936, Karl Ziegler proposed that anionic polymerization of styrene and butadiene by consecutive addition of monomer to an alkyl lithium initiator occurred without chain transfer or termination. Twenty years later, living polymerization was demonstrated by Michael Szwarc and coworkers. In one of the breakthrough events in the fiel ...

Alkyllithium
In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds. These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation. Organolithium reagents are used in industry as an initiator for anionic polymerization, which leads to the production of various elastomers. They have also been applied in asymmetric synthesis in the pharmaceutical industry. Due to the large difference in electronegativity between the carbon atom and the lithium atom, the C−Li bond is highly ionic. Owing to the polar nature of the C−Li bond, organolithium reagents are good nucleophiles and strong bases. For laboratory organic synthesis, many organolithium reagents are commercially available in solution form. These reagents are highly reactive, and are sometimes pyrophoric. History and deve ...

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 ...

Scientists From Shanghai
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

University Of Akron Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...
