    • Leon B. Levy is a Research Associate at the Corpus Christi Technical Center of Celanese Chemical Company (a subsidiary of Hoechst Celanese Corporation) where he has worked since 1962. He received his B.A. degree from New York University in 1958 and his A.M. and Ph.D. degrees in physical-organic chemistry from Harvard University in 1959 and 1962. His work involves studies in the mechanisms, kinetics and thermodynamics of free radical polymerization inhibition, and of heterogeneous catalysis. He is Celanese's representative to the Intercorporate Committee on Acrylate Monomer Safety and Handling.


Polymerization inhibitors are used in the processing and storage of acrylic acid. Depending upon the inhibitor and the conditions, it is sometimes imperative that oxygen be present for inhibitor “activation.”
