Some results on irradiation crosslinked isoprene networks, together with data from the literature on other networks are used to study the general behaviour of the reduced shear compliance J(φ)/J(l) in dependence on the polymer volume fraction φ up to the equilibrium swelling. Within the limit of the uncrosslinked melt, the φ −2-law for the plateau compliance is interpreted by multiple-step intra meander shear. Its other limit, a φ−2/3-law, already reached at medium crosslinking, appears simply as the (one-step) intrameander shear of the isotropically swollen blocks.
