Synthetic Rubber [1080p]

The development of synthetic rubber was driven by economic shifts and global crises:

The Evolution of Synthetic Rubber: From Wartime Necessity to Modern Essential synthetic rubber

Today, specialized varieties are engineered for specific industrial needs: The development of synthetic rubber was driven by

: The most significant leap occurred during WWII when the Allies lost access to 90% of the world's natural rubber supply. In response, the U.S. government launched an industrial policy triumph, scaling the production of Buna S (Styrene-Butadiene Rubber or SBR) to fuel the war effort. : In 1860, Greville Williams identified isoprene as

: 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 is an artificial elastomer—a long-chain polymer designed to replicate or improve upon the physical and chemical properties of natural rubber. While natural rubber is harvested from the sap of Hevea brasiliensis trees, synthetic rubber is primarily synthesized from petroleum-derived monomers. The History of Innovation

: 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
