Definitions
Polymer is a substance consisting of macromolecules of different lengths, which have a long sequence of one or more groups of monomeric units (shorter molecules) linked together with a primary or covalent chemical bond.
Time-dependent mechanical property is the characteristic of a polymer (or any other viscoelastic material) that interrelates the cause in the form of stress or strain and the time-dependent response (in the form of increasing strain or decaying stress).
Time-pressure superposition principle claims that material function can be generated by shifting isobaric segments of time-dependent mechanical properties measured at different pressures along the logarithmic time scale in respect to the segment selected at reference pressure.
Compressibility is a measure of relative change of the volume of polymer exposed to the pressure change.
