No matter how many indigenous herbs could be collected, this cmde drug supply needed to be made into medicine, and thus the accumulation of plant stores did not remove the necessity for an infrastructure of manufacture. Medicinal substances, whether botanical or chemical, usually needed some processing from their natural state. Without anything near the industrial capacity of Tilden and Company, Rosengarten and Sons, Powers and Weightman, Edward R.

The development of synthetic rubber played a special role in the history of polymerization chemistry. This was due primarily to the fact that attempts to synthesize rubber were made long before there was even the faintest idea of the nature of polymerization reactions. Such attempts began very soon after the elegant analytical work of Williams [1] in 1860, which clearly demonstrated that Hevea rubber was composed of isoprene. Thus, Bouchardat [2] in 1879 was actually able to prepare a rubberlike substance from isoprene (which he obtained from rubber pyrolysis), using heat and hydrogen chloride. Tilden [3] repeated this process in 1884 but used isoprene obtained from pyrolysis of turpentine to demonstrate that it was not necessary to use the mother substance of rubber itself. These explorations were soon followed by the work of Kondakow (1900) [4] with 2,3-dimethylbutadiene, that of Thiele (1901) [5]...
