Title (EN) ADDITIVE COMPOSITION AND METHOD
(FR) COMPOSITION ADDITIVE ET PROCÉDÉ
Abstract:
(EN) An additive comprising an active; the interfacial polymerization reaction product of a (poly)isocyanate and a polyamine; a copolymer having maleic anhydride-based repeat units and either or both of olefinic or styrenic-based repeat units; wherein at least a portion of the maleic anhydride-based repeat units are neutralized. A method of preparing an additive comprising providing an oil phase comprising an active, a solvent, a (poly)isocyanate; providing an aqueous phase comprising water and an emulsifier; mixing the oil phase and the aqueous phase to provide an emulsion; providing a polyamine to the emulsion; providing an aqueous dispersion or solution comprising a copolymer having maleic anhydride-based repeat units and either or both of olefinic or styrenic-based repeat units; wherein at least a portion of the maleic anhydride-based repeat units are neutralized; and cofeeding the emulsion and the aqueous dispersion or solution to a spray dryer.
(FR) L'invention concerne un additif comprenant une matière active ; le produit de la réaction de polymérisation interfaciale d'un (poly)isocyanate et d'une polyamine ; un copolymère ayant des motifs répétitifs à base d'anhydride maléique et des motifs répétitifs à base oléfinique et/ou à base styrénique ; au moins une partie des motifs répétitifs à base d'anhydride maléique étant neutralisés. Elle porte sur un procédé de préparation d'un additif, comprenant la fourniture d'une phase huileuse comprenant une matière active, un solvant, un (poly)isocyanate ; la fourniture d'une phase aqueuse comprenant de l'eau et un émulsifiant ; le mélange de la phase huileuse et de la phase aqueuse pour fournir une émulsion ; la fourniture d'une polyamine à l'émulsion ; la fourniture d'une dispersion ou d'une solution aqueuse comprenant un polymère ayant des motifs répétitifs à base d'anhydride maléique et des motifs répétitifs à base oléfinique et/ou à base styrénique ; au moins une partie des motifs répétitifs à base d'anhydride maléique étant neutralisés ; et l'introduction simultanée de l'émulsion et de la dispersion ou de la solution aqueuse dans un sécheur par atomisation.
