Coarse-grain models exhibit faster dynamics compared to all-atom models (see ref. 29-31 and references therein). Therefore, dynamical processes occur in coarse-grain simulations faster than what one would expect to observe in experiment. The scaling factor needed to convert times in this study's coarse-grain simulations to their approximate experimental equivalents was obtained by monitoring in silico the center-of-mass diffusion of polymer chains in a n-C 480 H 962 melt at 448 K, and comparing the extracted diffusion coefficient to a previously established experimental relationship between molecular weight and self-diffusion coefficients at 448 K for linear PE samples ranging in molecular weight from 600 to 120,000 g/mol. Accordingly, the dynamics of SDK PE chains at 448 K are approximately 4.07 times faster than those in experimental systems. As such, the aforementioned time steps of 5.0 fs and 2.5 fs correspond to ∼20.4 fs and ∼10.2 fs.
