<p>The invention relates to a multi-step method for producing gas-filled microcapsules with a narrow size distribution. In one process step the envelope-providing substance(s) is/are polymerized and in a spatially and/or temporally separate step the microcapsules are formed by a building-up process. This building-up process is initiated by the low-energy introduction of a defined amount of the gas to be encapsulated using a porous membrane with small defined pores.</p> |
