Abstract

Monte-Carlo simulations of reversible aggregation on a cubic lattice were done by introducing a finite probability (P) of nearest neighbours to form a hood. Depending on the volume fraction of occupied sites (phi) and P we observed different phenomena by monitoring as a function of time the space filling and the distribution of the aggregates and the gel fraction. At smaller values of P the system develops into an equilibrium distribution of aggregates of which the average size increases with increasing phi until abovea critical value the system percolates. At larger values of P the system phase separates into two phases with different densities. Above a critical value of phi the system percolates during a finite time. The life time of the gel and the maximum gel fraction were studied as a function of P.
