The dependence of the scattered intensity on angles was measured by SAXS for a series of samples taken during the span process of the gelation of styrene with divinylbenzene. Based on these data. we obtained the fractal dimensions and their evolution for both sols and gels successfully.

Key words: Gelation, Fractal geometry, SAXS, St-DVB
