WebbThe chemical constitution and physical state of natural rubber in its viscous, high-elastic and crystalline conditions are described. It is shown that those depend on long hydro-carbon chains which are normally coiled and tangled. The high elasticity of rubber is made possible by the ability of the chains to straighten and recoil. Webbrubbers have only moderate physical properties but good abrasion and excellent oil and hydrocarbon solvent resistance. However, they are not suitable for use with polar solvents. Nitrile rubbers also have low gas permeability particularly those with high nitrile content
