Effect of diffusivity for monomer supplied at t = 0: (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 = 10) vs. x for simulations with initial monomer supply. Solid curves are for simulations which start with c₁(x, 0) given by Eq. (45) with ε = 0.1 and S_i = 1. D = D₁ = 0 (black), D = D₁ = 0.005 (red), D = D₁ = 0.01 (blue), D = D₁ = 0.02 (green). The dashed black lines are for a simulation with uniform initial monomer concentration c₁(x, 0) = 0.2.
