Dr. Henry Kingston Hall Jr. is an internationally recognized polymer chemist, whose contributions to science are located at the interfaces between synthetic organic chemistry, physical organic chemistry and polymer chemistry. He developed novel monomers that led to useful, new polymers and provided invaluable insights into polymerization mechanisms. Particularly noteworthy is his work on the polymerization of CC-single bonds in bicyclobutanes and other bicyclic compounds[1,2,3] and the spontaneously occurring copolymerizations of electron-rich and electron-poor olefins.[4,5,6] His work has been laid down in approximately 450 publications. Hall was awarded several times including with the 1996 ACS Award in Polymer Chemistry and the ACS Division of Polymer Chemistry 2000 Herman F. Mark Polymer Chemistry Award.
