Butadiene Polymers. The most useful of these units is butadiene, a liquid closely related to butane, hence easily made from natural gas, petroleum refinery vapors or (less easily) from alcohol. Buna, butyl, Ameripol and Perbunan are all based on butadiene...
Four other elastomers are made from butadiene: Perbunan, Chemigum, Hycar and Ameripol. Perbunan is made with acrylonitrile but the formulas of the others have not been published. All are highly resistant to oil and are used for oil hose, gasoline hose and gaskets. Hycar makes an excellent ebonite, or hard rubber, when vulcanized. Ameripol is featured for tires by Goodrich. None of these is included in the Baruch program; they are in production without emergency Government financing...
...said German Army trucks often had to be jacked up overnight so that their solid tires would not flatten out permanently under their weight. German chemists soon discovered ways to make superior products by combining butadiene with other substances and co-polymerizing, making a rubber called Buna-N or Perbunan and another called Buna-S, widely used in Germany for auto tires. Both are now made in the U.S. by Firestone...
...tire manufacturers and military men, Standard's new plant held no hope of Buna tires by Christmas. Its first product will be Buna-N (also known as Perbunan), a rugged synthetic to compete with neoprene. etc. in the specialty trade and to replace German imports of Buna-N (some 340.000 Ib. in 1938), now cut off by war. But Standard Oil Co. (N. J.) also has U. S. rights for the manufacture of tire-Buna (Buna-S) and U. S. rubbermen hope for eventual independence from a tree-grown, seaborne, cartel-priced raw material...
