A significant body of evidence indicates that particles with excessively high or low mobility relative to Brownian particles form in dynamic equilibrium in glass-forming liquids. We examine whether these "dynamic heterogeneities" can be identified with a kind of equilibrium polymerization. This correspondence is first checked by demonstrating the presence of a striking resemblance between the temperature dependences of the configurational entropy s(c) in both the theory of equilibrium…

Advances in the generalized entropy theory of glass-formation in polymer melts.
TLDR
The generalized entropy theory of polymeric glass-forming liquids is reformulated into a computationally simpler and more natural formalism that greatly facilitates establishing essential trends in the dependence of the segmental relaxation time τ, fragility, characteristic temperatures of glass-formation, etc., on the combined influences of monomer molecular structure, chain rigidity, and cohesive interaction strength.
Equation of State and Entropy Theory Approach to Thermodynamic Scaling in Polymeric Glass-Forming Liquids
Numerous experimental and computational studies have established that most liquids seem to exhibit a remarkable, yet poorly understood, property termed ‘thermodynamic scaling’ in which the structural…
Tuning polymer melt fragility with antiplasticizer additives.
TLDR
A polymer-diluent model exhibiting antiplasticization has been developed and characterized by molecular dynamics simulations, and the dynamic propensity (local Debye-Waller factor p) does seem to provide a strong correlation with local molecular displacements at long times.
Thermodynamic scaling of dynamics in polymer melts: predictions from the generalized entropy theory.
TLDR
The efficiency of packing the polymers is established as the universal physical mechanism determining both the fragility and the scaling exponent γ, and the computed trends agree well with available experiments.
Universal nature of dynamic heterogeneity in glass-forming liquids: A comparative study of metallic and polymeric glass-forming liquids.
TLDR
An examination of particles having a locally preferred atomic packing, and clusters of such particles, suggests that there is no one-to-one relation between these populations of particles so that an understanding of the origin of DH in terms of static fluid structure remains elusive.
Growth of equilibrium polymers under non-equilibrium conditions
We investigate the kinetics of self-assembly by means of Brownian dynamics simulation based on a idealized fluid model (two 'sticky' spots on a sphere) in which the particles are known to form into…
Generalized Entropy Theory of Glass Formation in Polymer Melts with Specific Interactions
Chemical structure has been long recognized to greatly influence polymer glass formation, but a general molecular theory that predicts how chemical structure determines the properties of…
Fragility and cooperative motion in a glass-forming polymer-nanoparticle composite.
TLDR
This work systematically considers how Tg and m vary both for the material as a whole, as well as locally, for a range of nanoparticle concentrations and two polymer-NP interactions, and finds large positive and negative changes that can be interpreted in terms of the Adam-Gibbs model of glass-formation.
Evolution of collective motion in a model glass-forming liquid during physical aging.
TLDR
This work test the relationship between an estimate of the size of the cooperative rearrangements taking the form of strings and the effective structural relaxation time predicted by the Adam-Gibbs relationship for both an equilibrium supercooled liquid and the same fluid undergoing physical aging towards equilibrium after a series of temperature jumps.
The relationship of dynamical heterogeneity to the Adam-Gibbs and random first-order transition theories of glass formation.
TLDR
This work examines common measures of dynamical heterogeneity for a model polymer melt and finds that the string size appears to be the most consistent measure of CRR for both the AG and RFOT models.

Fragility of glass-forming polymer liquids.
TLDR
A generalized entropy theory of polymer glass-formation that combines the Adam-Gibbs model for the rate of structural relaxation with the lattice cluster theory for polymer melt thermodynamics introduces separate definitions of fragility for each temperature regime.
The shapes of cooperatively rearranging regions in glass-forming liquids
The cooperative rearrangement of groups of many molecules has long been thought to underlie the dramatic slowing of liquid dynamics on cooling towards the glassy state. For instance, there exists…
Equilibrium polymerization in the Stockmayer fluid as a model of supermolecular self-organization.
TLDR
It is found that the basic interaction parameters describing polymerization and phase separation in the SF can be estimated based on the existing theory of equilibrium polymerization, but the theory must be refined to account for ring formation in order to accurately describe the configurational properties of this model self-organizing fluid.

TLDR
Insight is obtained into the common appearance of asymmetric phase boundaries in a wide range of "complex" fluids and into the observation of apparent mean field critical behavior even rather close to the critical point.

We develop an analytic theory to estimate the glass transition temperature T(g) of polymer melts as a function of the relative rigidities of the chain backbone and side groups, the monomer structure,…

TLDR
It is shown that the Stokes-Einstein relation between the shear viscosity and the self-diffusion coefficients starts to break down in the temperature range where the ergodic convergence times increase dramatically.
