John E. Bercaw (born December 3, 1944) is an American chemist and Centennial Professor of Chemistry, Emeritus at the California Institute of Technology. [1][2]
Born in Cincinnati, Ohio, Bercaw obtained his Ph.D. from the University of Michigan in 1971 under the direction of Hans-Herbert Brintzinger, followed by postdoctoral research with Jack Halpern at the University of Chicago. [3]
He joined the faculty at the Caltech in 1972. Bercaw was elected a Fellow of the American Academy of Arts and Sciences in 1991.[4]
He is a member of the National Academy of Sciences (elected 1990), and he has received several national awards from the American Chemical Society (see below). [5]
His research interests are in synthetic, structural and mechanistic organotransition metal chemistry, including most recently catalysts for polymerization and trimerization of olefins and investigations of hydrocarbon hydroxylation; fundamental transformations and thermodynamics of organotransition metal chemistry; catalysts for hydrocarbon partial oxidation; catalysts for olefin trimerization and polymerization; homogeneous transformations of carbon monoxide and dihydrogen to fuels and chemicals.
Prof. Bercaw has greatly enhanced our understanding of the mechanisms of Ziegler-Natta (ZN) olefin polymerizations. This metal-catalyzed polymerization process is operated on a vast scale and produces, worldwide, over 200 billion pounds of polyolefins per year. Bercaw’s work has led to a fundamental understanding of the detailed mechanisms of chain growth in ZN polymerizations and the factors which control syndio- and isotacticities and the degree of comonomer incorporation in copolymerizations; these variables are critical in determining the physical properties of the resultant polymers and copolymers.
Commercial processes have been based on Bercaw’s discoveries. For example, new and superior ethylene/alpha-olefin copolymers are now industrially produced with titanium catalysts utilizing (η5- C5Me4)SiMe2NCMe3 and related ligands devised in Bercaw’s laboratories. These copolymers have proved to have superior properties. These types of systems have also allowed superior methods for production of ethylene/propylene and ethylene/propylene/diene elastomers.
