Processes to prepare aqueous polymer dispersions are provided, as well as compositions thereof, which have high solids content (e.g., 50%) with low viscosity. The process uses a selective hydrophilic macro-RAFT agent of formula (I), and is substantially free of surfactants. This process can be used to make latex polymers with good stability, which can be used widely in coatings (e.g., architectural paints, stone paints, industrial coatings, wood coatings, etc.), adhesives, sealants and mastic compositions.
