Abstract
Glassy polymers are used as dental materials because their rigidity enables them to support loads and to resist forces imposed in service in the oral cavity. Glassy polymers are generally regarded as amorphous and brittle. However, classification of these materials is very much a time-dependent concept, in which a brief experimental time interval generates brittleness, but an extended timescale can result in viscous flow. This time-dependent behavior of polymers is exemplified in the material known as “bouncing putty,” which flows like a viscous fluid when left under its own weight for extended periods, but shatters like a glass when hit with a hammer. Temperature is another factor that determines whether a polymer is a glassy solid, an elastic rubber, or a viscous liquid.
