METHOD FOR PRODUCING MICROCAPSULES

The invention relates to a method for producing microcapsules, comprising the following steps: (a) providing a first aqueous preparation containing at least one prepolymer; (b) providing a second non-aqueous preparation containing the active substance to be encapsulated; (c) mixing the aqueous and the non-aqueous phases in the presence of at least one emulsifier and/or stabilizer in order to forman emulsion; (d) polymerizing the at least one prepolymer contained in the emulsion from step (c) in order to obtain a dispersion of microcapsules that enclose the active substance; (e) hardening andcross-linking the microcapsules obtained in step (d); and optionally (f) removing the microcapsules from the dispersion and drying the microcapsules, the method being characterized in that the emulsion is formed in the presence of at least one 1,2-diol in step (c). 提出种制备微胶囊的方法，包括以下步骤：(a)提供含有至少种预聚合物的第水性制剂；(b)提供含有待包封活性物的第二非水性制剂；(c)在至少种乳化剂和/或稳定剂的存在下混合水性相和非水性相形成乳液；(d)使由步骤(c)得到的乳液中至少种预聚合物聚合得到包封活性物的微胶囊分散体(e)使由步骤(d)得到的微胶囊硬化和交联，以及
