Simulation Details: n-C 720 H 1442 was represented using the coarse-grain SDK model, which maps three methylene units to each coarse-grain bead. We have demonstrated that the SDK model is capable of capturing both the properties and behaviors of PE melts and PE crystallization. Previous work has demonstrated that polymer chains six entanglement lengths long exhibit entangled behavior, and SDK n-C 720 H 1442 chains are ∼7.6 entanglement lengths long, so this study's n-C 720 H 1442 melts correspond to entangled PE melts.
