Inventors Vinyl Invention Waldo L. Semon
By Mary Bellis

Polyvinyl Chloride (PVC)
PVC was first created by the German chemist Eugen Baumann in 1872. However it was never patented until 1913. Inventor, Friedrich Heinrich August Klatte initiated the polymerization of vinyl chloride with sunlight.  Klatte was the first person to receive a patent for PVC.

Waldo Lonsbury Semon worked for the B.F. Goodrich Company in the United States as a researcher. In 1926, Semon invented plasticized PVC or vinyl. He was trying to dehydrohalogenate PVC in a high boiling solvent in order to obtain an unsaturated polymer that might bond rubber to metal or for any other useful purpose.

Semon received United States patents numbers 1,929,453 and 2,188,396 for the "Synthetic Rubber-like Composition and Method of Making Same; Method of Preparing Polyvinyl Halide Products."
