The present invention provides for a method of producing a composition containing a polymer having undergone phase inversion, the method comprising the step of: effecting phase inversion of a phase invertible water insoluble polymer in an aqueous composition and the composition comprises a mixture of at least two different substances, one of which is a water insoluble dispersible polymer having undergone phase inversion while the other is optionally a contaminant.
L'invention concerne un procédé de production d'une composition contenant un polymère ayant été soumis à une inversion de phases. Le procédé comporte l'étape consistant à soumettre à une inversion de phases, dans une composition aqueuse, un polymère insoluble dans l'eau et pouvant subir une telle inversion. La composition comprend un mélange d'au moins deux matières différentes, l'une d'entre elles étant le polymère dispersable insoluble dans l'eau ayant été soumis à une inversion de phases, et l'autre étant un contaminant éventuel.
