We have developed a reversible diffusion-limited aggregation model for self-assembling polymers, which contain an associating site at each end of the chain. The simulations show that the associating sites form finite-sized clusters that are interconnected by intervening chains in a three-dimensional network. The average cluster size is seen to decrease with an increase in $\tau$ (the residence time of the chain in the cluster).
