This effort culminated in Union Carbide designing (along with the Kellex Corporation), building, and operating the massive K-25 gaseous diffusion plant at Oak Ridge.
Every company was run in a different way, and often it took some inquiring to find out who was the driving spirit, the executive with the real power of authority in a large corporation.
It was common knowledge at Union Carbide that one of the driving forces behind the company's spectacular growth was the executive vice-president, James A. Rafferty.
"[19] An executive with drive and vision, Rafferty contributed tremendously to the birth and fantastic growth of a new industry in America: synthetics made from petroleum rather than from coal, as they had been formerly.
As for Rafferty, he was a firm believer in the American system of free enterprise and the importance of industry's participation in the war effort.
"[11] Rafferty was impressed by Groves's earnest persuasion; he promised to discuss the matter with the top people of those Carbide units that would be involved.

Rafferty led Union Carbide's efforts in producing butadiene which would then be polymerized in a synthetic rubber production process.

[25][26] The Carbide and Carbon Chemicals Corporation should be extremely proud of the part it has played in the success of the synthetic rubber program.
