The present invention is a method for the preparation of porous particles that includes dissolving a polymer material in a first organic solvent and adding a second organic solvent and nonionic organic polymer particles to form an organic phase. The organic phase is dispersed in an aqueous phase that includes a particulate stabilizer to form a dispersion and the dispersion is homogenized. The first and second organic solvents are evaporated and the product is recovered.
