抜粋

The concentration dependence of characteristic time τr for self-diffusion coefficient Ds of linear polymers in good solvents was discussed in comparison with that of the weightaverage relaxation time τw for viscoelastic properties. Similarities were found for the concentration regions of τr, and τw, and also for the concentration dependences of τ's in the respective regions. On the basis of the similarities, it is pointed out that almost all the Ds data of polymers at finite concentrations so far published should not be discussed in terms of the reputation model since the solutions are not regarded as those in the well entangled regions.
