  • PROCESS FOR THE PREPARATION OF HIGH-SOLIDS, LOW-VISCOSITY LATEX USING SELECTIVE HYDROPHILIC MACRO-RAFT AGENTS
    Publication number: 20220195077
    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.

  • Process of making aqueous dispersions of polymers, emulsions of polymers, and use thereof
    Patent number: 9422671
    Abstract: The present invention relates to a process of making aqueous dispersions of copolymers, for example based on conjugated, aliphatic dienes and vinyl aromatic compounds. It relates also to the emulsions polymers obtained thereby, and to the use thereof as binders for the coating of paper. The invention also related to a coated paper having a coating comprising the emulsion copolymer. The process involves using at least two emulsifiers.
