Predicting Solute Diffusivity in Polymers Using Time–Temperature Superposition

The Journal of Physical Chemistry B, 2022
We demonstrate a novel application of the time-temperature superposition (TTS) principle to predict solute diffusivity D in glassy polymers using atomistic molecular dynamics simulations. Our TTS approach incorporates the Debye-Waller factor ⟨u2⟩, a measure of solute caging, along with concepts from thermodynamic scaling methods, allowing us to balance

Time‐temperature superposition in two‐phase polyblends

Polymer Engineering & Science, 1974
AbstractThe temperature dependence of the mechanical properties of a 50/50 blend of PVAC and lightly crosslinked PMMA has been examined using the data of Kawai et al. The shift distances, log aT, were generated by bringing the experimental data into coincidence on master curves calculated from a Takayanagi model whose parameters were varied in ...

Time-temperature superposition. Review

Polymer Mechanics, 1976
Experimental attempts to confirm the applicability of time-temperature superposition as a means of predicting the deformation of polymeric materials are reviewed. Examples of the use of the method for the accelerated testing of amorphous and crystalline thermoplastics, thermosets, and composites are presented.

Time-temperature superposition principle for bituminous mixtures

Revue européenne de génie civil, 2009
ABSTRACT In the small strain domain (amplitudes below about 10−4), when considering 1D approach, the bituminous mixtures behaviour is linear viscoelastic, with a great thermal sensitivity and respects the Time-Temperature Superposition Principle (TTSP). In this paper, the generalisation of the TTSP is proposed for 3D.

Time‐temperature superposition in thermorheologically complex materials

Journal of Polymer Science Part C: Polymer Symposia, 1971
AbstractTwo‐phase polymeric materials such as polymer blends, block copolymers, and graft copolymers, are thermorheologically complex. Mechanical response curves obtained on such materials at different temperatures cannot, in principle, be brought into superposition by a simple shift along the logarithmic time or frequency axis.
