Abstract (en)
[origin: WO9715617A1] A water-redispersible powdered composition produced by mixing then drying an emulsion of at least one water-insoluble film-forming polymer, at least one main surfactant and at least one water-soluble compound, is disclosed. The composition includes an emulsion of at least one water-insoluble film-forming polymer prepared from ethylenically unsaturated monomers; at least one main surfactant with a binary water-surfactant phase diagram comprising an isotropic phase that is fluid at 25 DEG C up to a surfactant concentration of at least 50 wt %, followed by a hexagonal or cubic rigid liquid crystal phase at higher concentrations, said liquid crystal phase being stable at least up to the drying temperature; and at least one water-soluble compound. A method for preparing said composition, and the use thereof, are also disclosed.
