Abstract
The formation of polymer networks (gelation process) was studied by a numerical simulation of a lattice spin model with 3 states, which allo ws the representation of simple diffusion and aggregation processes. N ear the percolation threshold, p(c), the same critical exponents were detected as in the usual diffusion-free classical percolation theory. Only non-universal values (for example p(c)) show a significant depend ence on the ratio between diffusion and reaction constants.
