摘要：
The invention relates to processes for preparing a synthetic foam having present therein particles with a controlled particle distribution and the use of said foam, as well as to foams as such. Accordingly the invention is directed to a process for preparing a synthetic foam having present therein particles, wherein the distribution of said particles is controlled by the following steps of dissolving at least one synthetic polymer in one or more solvents to form a solution； contacting particles with said solution to form a polymer/particles mixture； and freeze-drying the polymer/particles mixture by: freezing the polymer/particles mixture； and subsequently subliming the one or more solvents to form a synthetic foam comprising said particles.
