摘要：

The sol-gel transition in the poly(methyl methacrylate)/butyl acetate system has been studied using quasielastic light scattering spectroscopy. Critical dynamical behavior is observed near the sol-gel transition that is characterized by the presence of a power-law spectrum of relaxation times. The results have been interpreted in terms of a simple cluster diffusion model. The experimental results favor the percolation model.
