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: The present invention relates to compositions, preferably a hard surface treatment composition, comprising: at least a polymer comprising one or more types of monomer units selected from the group consisting at least one cationic or amphoteric monomer unit, a multifunctional organic acid, and a nonionic or amphoteric surfactant. The invention also refers to the use of such compositions for killing pathogens on a surface over an extended period of time by applying a long-lasting composition to the surface.

Abstract: The present invention relates to the preparation of block copolymers which are particularly useful as a rheology agent, and which are suitable, inter alia, for oil extraction, which comprises a step of radical polymerization in which the following are brought into contact, in an oily medium:
monomers dissolved in the oily medium;
monomers which are insoluble in the oily medium, in the form of a micellar solution;
at least one radical polymerization initiator; and
preferably at least one radical polymerization control agent.
The invention also relates to the polymers obtained by this process and the use thereof as surfactants or dispersants.-

Abstract: Described herein is a method for treatment of a metallic surface, including the step of (A) contacting the metallic surface with a first aqueous composition, and a subsequent step of (B) contacting the metallic surface subsequent to step (A) with a second aqueous composition. Also described herein is a kit-of-parts including the first and second aqueous composition and a kit-of-parts including master-batches of the first and second aqueous compostions. Also described is a method of using the kit-of-parts for treating a metallic surface and substrates including the thus treated metallic surfaces.

Abstract: The present disclosure relates to a new method for producing alkali salt of bis(fluorosulfonyl)imide of high purity, as industrial scale, and with a reasonable cost when compared to the other available methods. Said method comprises the steps of reacting a bis(chlorosulfonyl)imide or a salt thereof with an onium chloride to produce an onium salt of bis(chlorosulfonyl)imide; reacting an onium salt of bis(chlorosulfonyl)imide with anhydrous hydrogen fluoride in at least one organic solvent to produce onium salt of bis(fluorosulfonyl)imide; and reacting the onium salt of bis(fluorosulfonyl)imide with an alkali salt to obtain alkali salt of bis(fluorosulfonyl)imide.
