Tuning polymer melt fragility with antiplasticizer additives
Moreover, the addition of antiplasticizing particles renders the polymer melt a stronger glass-forming material as determined by changes in the characteristic temperatures of glass formation, the fragility parameter D from fits to the Vogel-Folcher-Tamman-Hesse equation, and through the observation of the temperature dependence of the size of

Tuning Polymer Melt Fragility With Antiplasticizer
Tuning Polymer Melt Fragility With Antiplasticizer Additives Published June 19, 2007 Author (s) Robert A. Riggleman, Jack F. Douglas, J J. de Pablo Abstract A polymer-diluent model exhibiting antiplasticization has beendeveloped and characterized by molecular dynamics simulations.
Tuning the Fragility of Polymer Melts With
Using molecular dynamics simulations, we have developed and analyzed a model that exhibits antiplasticization behavior by decreasing the glass transition temperature, increasing the density of the system below the glass transition temperature of the pure melt, and increasing the high frequency shear modulus.
Tuning polymer melt fragility with antiplasticizer
coarse-grained model of a polymer melt with and without an antiplasticizer additive. The pure polymer melt has been ex-tensively characterized in previous works,13,16–18 and here we merely provide its main elements. Each polymer molecule consists of 32 Lennard-Jones spherical interaction sites con-nected by harmonic springs with a force
