Relaxation of open sticker concentration c_open(t) in the anomalous diffusion regime of bond formation in hybrid polymer network (thick lines) following an energy (ε)-jump up of the bond strength from the state with high initial concentration of open stickers $c_{\mathit{open}}^i>c_{\mathit{open}}^{\ast }\approx 1/R_0^3$ to the states with lower final concentrations of open stickers $c_{\mathit{open}}^f$ still above $c_{\mathit{open}}^{\ast }$. The thin line corresponds to equilibration at higher final concentration of open stickers $c_{\mathit{open}}^{f,2}>c_{\mathit{open}}^{f,1}>c_{\mathit{open}}^{\ast }$ and takes shorter time ${\tau }_{eq}^2={\tau }_{\mathit{open}}^{f,2}<{\tau }_{eq}^1={\tau }_{\mathit{open}}^{f,1}<{\tau }_R$ to equilibrate.
