The ratio gη between the values of the intrinsic viscosity of the Kratky–Porod wormlike regular four-arm star and linear touched-bead models, both having the same total contour length L and bead diameter db (in units of the stiffness parameter), is numerically evaluated in the Kirkwood–Riseman approximation. Its behavior as a function of L and db is examined (solid curves) and is compared with previous results for the three-arm star (dashed curves).
