    • If a chain system is near the glass transition, the stress relaxation becomes extremely slow and nonlinear shear regimes are realized even at very small shear rates. See calculations of G(t) and rheology in such a system [24,33].

    • note
    • BTn for various T as the proportionality coefficient of the relation in Eq. (28). See Fig. 6 of Ref. [24]. This expression also holds in the present work and is thus independent of N.
