Monte Carlo simulations of bulk polyethylene were performed on a high-
coordination lattice. In this study, we investigated the effect of coa
rse-grained short and long range interaction parameters on the dynamic
properties of the bulk system. As a result of fine tuning of the simu
lation parameters, our coarse-grained simulations were successful in m
imicing the local and large-scale dynamics of C44H90 and C100H202 melt
