Crude rubber is a tough and an elastic solid. It becomes soft and sticky as the temperature rises. Its specific gravity is 0.915. The most important property of natural rubber is its elasticity. When stretched, it expands and attains its original state, when re..

The most important property of natural rubber is its elasticity. When stretched, it expands and attains its original state, when released. This is due to its coil-like structure. The molecules straighten out when stretched and when released, they coil up again. Therefore a..

Semi synthetic polymers are derived from naturally occurring polymers by chemical modifications. Examples: Vulcanized rubber, gun cotton and cellulose diacetate. Vulcanized rubber is used in making tyres. Gun cotton which is cellulose nitrate is used in making explosiv..
