摘要：

We have measured cooperative diffusion coefficients Dc of different silicone polymer networks at equilibrium swelling by using the quasielastic light scattering technique. The model networks have been prepared by tetrafunctional endlinking of linear chains having different molecular masses. Dc is a function of the molecular mass of the network chains and the swelling degree at equilibrium, which can be described by scaling laws. The existence of a slow mode motion, similar to that in concentrated polymer solution, could be shown.
