Abstract: 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.

Abstract: Paint, clear coat, stain, adhesive, or other aqueous formulations that contain at least one [(dimethylamino)alkyl]-imino-dialcohol and a alkyd emulsion, polymer latex or polyurethane dispersion binder. Also disclosed are methods for manufacture and use of these formulations. The [(dimethylamino)alkyl]-imino-dialcohols provide aqueous formulations having low odor and reduced volatile organic compounds (VOC). The [(dimethylamino)alkyl]-imino-dialcohols also aid in dispersing pigment and other solids so less co-dispersant is needed for aqueous paint or coating formulations.
