MULTI-STAGE METHOD FOR PRODUCUNG GAS-FILLED MICROCAPSULES |
摘要 |
The invention relates to a multi-stage method for producing gas-filled microcapsules. In one stage of the method, the substance that forms the coat is polymerized. The microcapsules are formed in a physically and/or temporally separate stage, by means of a structuring process. The polymerization is carried out with moderate stirring, while the microcapsules are structured in dispersing conditions. |
