Figure 5.

Results for diffusion of the two dye probes in the swollen PDMS networks as a function of Q. (a,b) Reduced diffusion coefficients. For comparison, the solid lines are again the best fits of the solution data to the Phillies model. (c,d) Translational probability P_x as evaluated from eq 3. The dotted lines are guides to the eye and, in (c), estimated plateau values are indicated as solid lines. (e,f)Effective relative friction coefficients due to cross-links, ζ_x/ζ₀, as evaluated from eq 6. The solid lines in (e) are fits to a power-law function, and the dotted lines in (f) are guides to the eye.
