Walter H. Waddell is a retired ExxonMobil Chemical senior research associate and consultant to the tire and rubber industry with expertise in silica technology, [1] rubber compounding, [2] butyl polymer applications [3] and tire aging. [4] Since 2015 he has served on the technical committee of the International Tire Exhibition & Conference (ITEC) for Tire Manufacturing. [5]
Waddell received his BS in Chemistry at University of Illinois Chicago in 1969 and his PhD from University of Houston in 1973. He held a postdoctoral research position at Columbia University until 1975.
Waddell's first professional post was as an associate professor of chemistry at Carnegie-Mellon University. In 1983 he joined Goodyear research as a section head. In 1990 he joined PPG Industries as a senior scientist developing silica technology. In 1996 he joined ExxonMobil as a senior research associate in specialty Polymers Technology, retiring in 2015. Following his retirement, he has consulted on rubber technology for Cheng Shin Rubber Industrial Co. Ltd. Oriental Silicas Corp. and Smithers. He holds an appointment as an adjunct professor at Beijing University of Chemical Technology. Since 2015 he has served on the technical committee of the International Tire Exhibition & Conference (ITEC) for Tire Manufacturing.
The Charles Goodyear Medal is the highest honor conferred by the American Chemical Society, Rubber Division. Established in 1941, the award is named after Charles Goodyear, the discoverer of vulcanization, and consists of a gold medal, a framed certificate and prize money. The medal honors individuals for "outstanding invention, innovation, or development which has resulted in a significant change or contribution to the nature of the rubber industry". Awardees give a lecture at an ACS Rubber Division meeting, and publish a review of their work in the society's scientific journal Rubber Chemistry and Technology.
The Melvin Mooney Distinguished Technology Award is a professional award conferred by the ACS Rubber Division. Established in 1983, the award is named after Melvin Mooney, developer of the Mooney viscometer and of the Mooney-Rivlin hyperelastic law. The award consists of an engraved plaque and prize money. The medal honors individuals "who have exhibited exceptional technical competency by making significant and repeated contributions to rubber science and technology".
Russell A. Livigni is a rubber industry scientist and executive noted for his discovery and development of high trans styrene-butadiene rubber, a crystallizing rubber that provides superior oxidation resistance relative to natural rubber.
The purpose of the Sparks–Thomas Award, given by the ACS Rubber Division, is to recognize and encourage outstanding contributions and innovations in the field of elastomers by younger scientists, technologists, and engineers. The award is named for Exxon scientists William J. Sparks and Robert M. Thomas, co-inventors of Butyl rubber.
