3.6. Solid Polymers
The behavior of polymers in the solid state is essential for the analysis of the demolding step of every replication process. Typically, the temperature range during demolding is near or below the glass-transition temperature or the crystallization temperature of a polymer. Solid polymers are also characterized by viscoelastic behavior. To describe viscoelastic behavior in the solid state, the models used to describe behavior in the melt state are valid.
3.6.1. Linear Viscoelasticity in the Solid State
Viscoelastic behavior in the solid state can also be described with the Maxwell element, a serial connection of a dashpot, and a spring. For a single element, the behavior of the element can be described by the differential ...
