Dr. Dean R. Rexford of the DuPont Organics Chemicals Department, Wilmington, Delaware, USA, credited with leading the development of Viton®, the world's fluoroelastomer.
The story began in April 1954, when Dr. Dean R. Rexford of the DuPont Organics Chemicals Department in Wilmington, Delaware, USA, was experimenting with a new elastomer with high temperature and chemical resistance. Unfortunately, there was one major barrier. Commercial scale polymerization of the materials used to make this product was considered a significant potential safety risk. It was up to Dr. Rexford, chemist and inventor, to tackle this issue. Following a controlled reaction involving hexafluoropropene, vinylidene fluoride and polymerization initiators, an elastic 60/40 HFP/VF2 copolymer was obtained.
