Effect of diffusivity for monomer supplied over time: (Left) Location of gel front x_g(t) vs. time, (middle) time course of total gelation ${\int }_{-L}^L{\theta }_g(x,t)dx$, and (right) final gel mass distribution (at t = 24) vs. x (right) for simulations which start with c_k(x, 0) = 0 and have a source of the form in Eq. (46) with S_m = 2, λ = 1. D = D₁ = 0.00 (black), D = D₁ = 0.005 (red), D = D₁ = 0.01 (blue), D = D₁ = 0.02 (green), and D = D₁ = 0.08 (magenta). Also shown are the results for a spatially uniform source with the same rate constant λ and with the same total amount of monomer (dashed black).
