PVC was prepared by the French chemist Henri Victor Regnault in 1835 and then via the German chemist Eugen Baumann in 1872, but it really wasn't patented right until 1912, when another German chemist, Friedrich Heinrich August Klatte, utilized sunlight to initiate the polymerization of vinyl chloride. Commercial software from the plastic was at first constrained by its Extraordinary rigidity; nonetheless, in 1926, though seeking to dehydrohalogenate PVC inside a superior-boiling solvent so that you can acquire an unsaturated polymer That may bond rubber to metallic, Waldo Lunsbury Semon, Doing work for the B.
