: In the 1950s, Karl Ziegler and Giulio Natta developed catalysts that allowed for the creation of "synthetic natural rubber" (cis-polyisoprene), which mimics the structure of tree-harvested rubber almost perfectly. Common Types and Their Applications
: In 1860, Greville Williams identified isoprene as the main constituent of natural rubber. By 1909, German chemist Fritz Hofmann succeeded in the first polymerization of methyl isoprene. synthetic rubber
