Fritz Klatte
Fritz Klatte (28 March 1880, Diepholz – 11 February 1934) was a German chemist and the discoverer of polyvinyl acetate, with German patent (GP 281687 1912) for its preparation from acetylene gas.
Polyvinyl chloride (PVC) was discovered by French physicist Henri Victor Regnault, and German physicist Eugen Baumann. Klatte designed the production process, although never successfully commercialised it. Klatte is sometimes incorrectly attributed to be the discoverer or inventor of PVC.
