The effects of functional group density of reactive latexes on the relative rates of interdiffusion and crosslinking reaction during film formation and annealing process were investigated. The average diffusion coefficient D of the polymer chain was evaluated from dynamic mechanical analysis and was correlated with the diffusion of polymer chains through particle-particle interfaces. In the film of the reactive particles, the magnitude of D was lower than that of the homopolymer film. These results consistently showed the dependence of chain mobility on tensile strength development of the film of the reactive latexes, in which the mobility of the chains was restricted, leading to the prevention of mechanical strength development.
