Webmodifications of the Flory–Fox equation that consider ‘dendrimer-relevant’ aspects such as the non-zero values of n e/M at infinite molecular weight. We also present a new approach using the geometric parameters of dendrimer mass evolution suggesting that the Flory–Fox equation is indeed appropriate for determination of dendrimer T gN. http://www.sciepub.com/reference/398829
