Kinetic regimes for bond formation in reversible polymer network following an increase of bond strength. Thick line: from the state with relatively high initial to low final concentrations of open stickers $c_{\mathit{open}}^f<c_{\mathit{open}}^{\ast }<c_{\mathit{open}}^{i,1}$; thin line: from the state with relatively low initial concentration of open stickers to the state with even lower final concentration of open stickers $c_{\mathit{open}}^f<c_{\mathit{open}}^{i,2}<c_{\mathit{open}}^{\ast }$. The equilibration from initial concentration of open stickers $c_{\mathit{open}}^i>c_{\mathit{open}}^{\ast }$ to the final concentration of open stickers $c_{\mathit{open}}^f<c_{\mathit{open}}^{\ast }$ corresponds to the formation of bonds in the mixed regime (thick line): for t < τ_R by anomalous diffusion while at longer times t > τ_b the remaining bonds form in the partner exchange regime.
