The next important structural characteristic for SCPs is the chain end-to-end distance L e and its distribution. Le quantifies how stretched polymer chains are in bulk and it is an important property by which the robustness of "soup" method in accurate representation of SCP microstructure can be evaluated. Figure (middle panel) shows the average, standard deviation from the average, and distribution of Le for all five polymers as obtained from "melt" and "soup" samples. Note that an estimation of contour length Lc of polymers (i.e., the length of a fully stretched chain) are given on each graph. As shown, similar to the torsional distribution, the "soup" method generates very similar Le and Le distribution as compared to the "melt" method for all polymers. Note that the difference in the averages obtained from the two methods is well below the standard deviations obtained from "melt" simulations.
