摘要： A method of manufacturing porous polymer particles with improved filterability is described. One or more first water phases are formed comprising an anionic hydrocolloid with a mass-per-charge value of less than 600 and a relatively minor amount, compared to the anionic hydrocolloid, of at least one of a nonionic, cationic, zwitterionic, or weakly anionic water soluble or dispersible polymer, where the weakly anionic water soluble or dispersible polymer has a mass-per-charge value of larger than 600. A water-in-oil emulsion is formed by dispersing the one or more first water phases into an organic phase comprising at least one of either (i) preformed polymer dissolved in an organic solvent or (ii) polymerizable monomers, and homogenizing. A water-in-oil-in-water multiple emulsion is formed by dispersing the water-in-oil emulsion into a second water phase containing a stabilizing agent and homogenizing. The organic solvent is removed to precipitate the preformed polymer, or the polymerizable monomers are polymerized, to obtain a dispersion of porous polymer particles in an external aqueous phase, wherein individual porous particles each comprise a continuous polymer phase and internal pores containing an internal aqueous phase. The dispersion of porous polymer particles is filtered to remove the external aqueous phase. The method enables increased filtration rates of porous polymer particle dispersions containing water in the pores.

摘要： The present invention is directed towards methods of manufacturing wax-containing polymer particles by limited coalescence processes employing aqueous wax dispersions. In one embodiment, an aqueous wax dispersion or emulsion is dispersed in an oil phase comprising a water-immiscible solvent and a polymer to form a transient water-in-oil (W/O) emulsion, and a further aqueous phase containing a particulate stabilizer is then added to the W/O emulsion to induce phase inversion, and the mixture homogenized to form an oil-in-water (O/W) emulsion. The solvent is then removed from the emulsion to form particles containing wax domains inside. In another embodiment, the aqueous wax dispersion is first mixed with the aqueous phase containing the particulate stabilizer, and homogenization is made with the oil phase to form an O/W emulsion, from which wax-containing particles are obtained after solvent removal. In still further embodiments, the aqueous wax dispersion is used in the second water phase of a double emulsion (W1/O/W2) process to form porous polymer particles containing the wax.
