摘要：

Small angle X-ray scattering (SAXS) was used to follow the evolution of Zr-tetrapropoxide + acetic acid mixtures. The formation of aggregates and their linkage during gelation was studied by measuring their gyration radii and the correlation and hydrodynamic lengths, applying the classical theory for solutions of macromolecular chains. The mechanism of aggregation was interpreted using basic fractal concepts.
