Type of dendritic core used (Dendron = bisMPA dendron, dendrimer = bisMPA dendrimer,), Pol = polymer precursor used for star-like polymer formulation
Molecular weights and dispersity were determined by SEC using multi-angle light scattering and refractive index detectors.
Hydrodynamic diameter was measured by DLS in 0.15M NaCl
