    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.
