The dynamical scaling of the chain-chain aggregation model is investigated in three dimensions. Monte Carlo simulations are performed on a cubic lattice with a diffusion coefficient proportional to kγ for a chain of mass k. At large times the mean chain mass grows like tz and the meansquare radius of gyration like t2z/D, where D is the fractal dimension of the chains. The relation z=(1-1/D+ϕ-γ)-1, obtained when one assumes that the sticking probability between two chains of mass k is proportional to k-ϕ, is checked numerically with ϕ(3D)≈0.72.
