Gary Ver Strate, Manalapan - Ricardo Bloch, Scotch Plains - Mark J. Struglinski, Bridgewater Exxon Chemical Company, Linden John E. Johnston, Warren Exxon Research and Engineering Co., Annandale Roger K. West, Montclair TThe five scientists, working in two different Exxon company divisions, combined to produce a completely novel material of significant commercial value, a new type of viscosity modifier. Marketed since 1987 by Exxon Chemical Company, these viscosity modifiers are a major class of lower viscosity lubricant additive for newer engine designs that provide balance between durability and fuel economy. Viscosity modifier polymers allow motor oils to be formulated with a low viscosity at low temperatures with less reduction of viscosity at higher engine operating temperatures. This provides easier cranking at low temperatures and lower friction and less bearing wear at high temperatures. This results in long engine life and reduction of fuel consumption for autos and trucks, thereby extending vehicle service life and making a real contribution to our national goal of conservation. Drs. Ver Strate, Bloch and Struglinski are affiliated with the Exxon Chemical Company in Linden. Gary Ver Strate holds a Ph.D. in physical chemistry from the University of Delaware. Ricardo Bloch graduated from California Institute of Technology in 1976 with a Ph.D. in chemical engineering. Mark J. Struglinski joined Exxon Chemical's Paramins Technology Division in 1984 after graduating from Northwestern University with a Ph.D. in chemical engineering. John E. Johnston serves as a section head in Exxon Research and Engineering Company's corporate research unit. He graduated from the University of Akron with a Ph.D. in polymer science in 1975. Roger K. West retired from Exxon in 1995 as an engineering associate. Today, he is president of West Technologies, Inc., a consulting firm that specializes in technical scientific information research, often for patent purposes. He holds a Ph.D. in chemical engineering.
