Fig. 8. (a) Chain end-to-end vector autocorrelation function Cee(t) at various NP volume fractions for N = 200. In every case Cee(0) = 1. (b) Average chain end-to-end relaxation time τ obtained from fitting of the stretched exponential function to the Cee(t) numerical values (corresponding stretched exponents β < 1 in Fig. S8, ESI†). Dash-dotted lines are guides to the eye.
