High pressure dynamics of polymer/plasticizer mixtures - NASA/ADS
We studied the pressure dependence of the glass transition temperature as well as the fragility of both the neat components and the mixtures at different concentrations (on the rich polymer range). Finally, the experimental data were rationalized within the framework of an Adam-Gibbs (AG) based approach recently developed [G. A. Schwartz et al
High pressure dynamics of polymer/plasticizer mixtures
The dynamics of these particular mixtures show only one main relaxation process contrarily to what is observed in athermal miscible polymer mixtures. From the dielectric spectra the maximum relaxation time as a function of pressure and temperature was obtained and analyzed.
High pressure dynamics of polymer/plasticizer mixtures: The
Plasticizers are usually added to polymers to give them the desired flexibility and processability by changing the dynamical properties of the polymer chains. It is therefore important to give a quantitative description about how the dynamic behavior of a given polymer is modified by the incorporation of a second component.
High pressure dynamics of polymer/plasticizer mixtures
Polymer/plasticizer mixtures are subjected to high pres-sures and temperatures during extruding, molding, and cur-ing processes, and it is therefore important to know how plasticizers modify the polymer dynamics under these con-ditions. Although there is still no appropriate framework to account for the pressure-temperature dynamics of the mix-
