Dynamic light scattering study of the radical copolymerization of styrene-meta divinylbenzene

摘要

We report a dynamic scattering study of a system undergoing irreversible gelation (styrene-divinylbenzene-AIBN-benzene). The autocorrelation function of intensity scattered from the sol exhibits two independently decaying modes. The slow-relaxation time follows the same time dependence as the macroscopic viscosity of the medium.
