The proportionality coefficient A in the relationship $k_{\text{eff}}=A{k}_0^{\delta }$ varies strongly as a function of the length scale of quenching and polymer length. Much of this variation is captured by the approximate formula A = a(1/τ_r)^1−δ, where τ_r is the polymer's inherent relaxation time (eq 23), a = 0.5, and the scaling exponent δ is estimated using the universal curve δ(g) of Figure 4b. The predictions of this formula are plotted as solid lines.
