Chain relaxation in melts of moderately entangled macromolecules presents the first signs of topological constraints that are commonly manifested in the rheology of long commercial-grade polymers. In this study, we employ multiscale molecular dynamics simulations to examine the relaxation characteristics of model …

Cross-linking macromolecules is an important process that aims to modulate the mechanical properties of elastomers and meet desired specifications based on the application sought. The impact of cross-linking density on rubber moduli has been well established by theory, experiments, and computational studies. …

a recently proposed crosslinking algorithm. The shear stress relaxation modulus and the mean square displacement (MSD) were calculated for all systems along with structural properties, such as the pair distribution function, angles and dihedral distributions, and statistical distributions of the atoms between …

The achievement of sufficient dispersion of vulcanization accelerators is critical to tailoring superior cross-linked elastomers. Modern recipes rely on multicomponent formulations with silica particles covered by coupling agents. We study the molecular properties of select accelerators in polyisoprene melts and their affinity …

Through the analysis of the spatial correlations of local stress, we detect the propagation of long-ranged liquid-elasticity-mediated shear stress waves in polymeric and low-molecular weight liquids. The propagation of shear waves is effectively planar; i.e., σ α β propagates in the α …
