Rubber
Rubber, rubber is described in the Encyclopaedia Britannica, Volume 19, 1965 edition: Rubber the substance caoutchouc (q.v.), a milklike fluid that is obtained from certain tropical shrubs or tyres and then subjected to various processes of manufacture; or it may be a product of chemical synthesis. The uniqueness of rubber lies in its physical properties of extensibility and toughness. In its natural state, it is greatly affected by temperature, becoming harder when cooled (at 0 x-10 x C it is opaque) and softer when heated (above 50x C it becomes tackier and less elastic, decomposing into liquid form at 190 x-200x C). When vulcanized (i.e. heated with sulfur at 120 x-160 x C) it loses its thermoplasticity and becomes stronger and more elastic..... Chemically, rubber is a polymer of isoprene..... The term synthetic rubber is used to describe an evergrowing number of elastic materials, some of which closely resemble natural rubber while others have completely different physical properti...
