Viscosimetric, hydrodynamic and conformational properties of dendrimers and dendrons were studied. The molecular conformation in solution and the melt that controls the efficacy in biocides, gene transfer and catalyst supportive applications was investigated with coarse grained simulations and extensive experimentation of x-ray light and neutron scattering and rheology. The radius of gyration was calculated from static scattering measurements while hydrodynamic radius was determined by light scattering and other diffusion measurements. Larger ratios were observed for polymers in solution.
