The authors wish to correct the abscissas of Figs. 5, 11–13, and 15 in this paper by replacing G0 by Gchain where Gchain is GchainG0/N, with N the average number of springs per chain. Figures containing the linear viscoelastic moduli have no such error. The caption of Fig. 5 should say that N=21. These changes do not affect the results, discussions, and conclusions of this study.
