In this study, we used coarse-grained molecular dynamics simulations with iterative defect removal algorithm to investigate structure-properties relationship of star polymer networks (SPNs) and telechelic polymer networks (TPNs). SPNs possess a mechanism that eliminates loop defects during network formation, resulting in a greater number of elastically effective junctions than in TPNs. Despite the differences in cross-linking mechanisms, both network types exhibit shear moduli approximately twice the value predicted by the phantom network model using the effective closed cycle density, independently on the number of branches or the binding ratios.
