    摘要: 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.

    摘要: Porous particles can be prepared using an evaporative limited coalescence process in which one or more discrete cavities are stabilized within the continuous polymeric solid phase of the porous particles. The one or more discrete cavities have inner walls and are dispersed within the continuous polymeric solid phase. The porous particles further comprise a cavity stabilizing hydrocolloid on the inner walls of the one or more discrete cavities, and an amphiphilic (low HLB) block copolymer that is disposed at the interface of the discrete cavities and the continuous polymeric solid phase.
