Rubber properties

the tendency of a solid material to move slowly or deform permanently

chemical substance

reversible transition in amorphous materials at which amorphous polymers go from hard to viscous

Viscoelasticity is a material property that combines both viscous and elastic characteristics. Many materials have such viscoelastic properties, especially materials that consist of large molecules. Polymers are viscoelastic because their macromolecules can make temporary entanglements with neighbouring molecules which causes elastic properties. After some time these entanglements will disappear again and the macromolecules will flow into other positions where new entanglements will be made (viscous properties).
