Synthetic Rubber
HAT about the synthetic rubbers that are being used to-day? They aim at imitating the properties of natural rubber rather than its exact chemical composition. Russia has developed a synthetic rubber from a substance which can be obtained from alcohol. The quality is inferior to natural rubber. The German Buna is better, while the American Duprene, called Neoprene in England, has remarkable resistance to oils, which spoil natural rubber, but Duprene is very expensive. And natural rubber is keeping ahead of the synthetic product.. As a result of biological research, the yield’ per acre has been about trebled, and despite the effect of factors such as the age of a tree, the season of the year, rainfall and soil, a product is obtained nearly as constant in composition as if made in a chemical works. I think the vastly increased life of motor car tyres shows the improvements in natural rubber processing which have been made-("The Changing Bases of Society" Discussion between K. B. Cumberland and H. N. Parton, BY¥A, June 25.)
