Randomly branched polystyrene (PS) was synthesized by end-linking monodisperse linear PS chains with divinylbenzene using controlled free radical polymerization. Samples obtained at different reaction extents were characterized using size exclusion chromatography and static and dynamic light scattering. The results are compared with those obtained on randomly branched poly(methyl methacrylate) (PMMA). The overal structure of branched PS was found to be the same as that of branched PMMA despite the very different local structure. The results strongly support the idea that the formation of polymeric gels is a universal process that may be described by the percolation model.< Réduire
