    • The invention relates to a method for producing fine particle suspensions by melt emulsification, comprising at least one material having a melting temperature above room temperature, comprising the following steps: (a) transferring at least one pre-emulsion comprising a continuous and a disperse phase in a rotor-stator machine, a rotor-rotor machine, or to a continuous and/or disperse phase; (b) optionally adding one or more further components to the at least one pre-emulsion in the rotor-stator machine; (c) emulsifying the at least one pre-emulsion by means of mechanical shearing and/or stretching and/or turbulence at a temperature no greater than 10 K above the melting temperature of the at least one material having a melting temperature above room temperature, or at a temperature no less than 10 K below and no greater than 10 K above the glass transition temperature or the melting temperature, as long as the material having a melting temperature above room temperature is a polymer, for producing a fine particle emulsion; and (d) cooling the fine particle emulsion for producing a fine particle suspension; wherein the disperse phase portion is in the range of 85% to 99.5% at least in step (c).
    • 本发明涉及通过熔融乳化生产细颗粒悬浮液的方法,其包括至少一种具有高于室温的熔融温度的材料,包括以下步骤:(a)转移至少一种包含连续分散相的预乳液 在转子 - 定子机器中,转子 - 转子机器,或连续和/或分散相; (b)任选地将一种或多种另外的组分添加到所述转子 - 定子机器中的所述至少一种预乳液中; (c)通过机械剪切和/或拉伸和/或湍流在至少一种熔融温度高于室温的材料的熔融温度不超过10K的温度下乳化所述至少一种预乳液, 或者在玻璃化转变温度或熔融温度以上不低于10K且不大于10K的温度下,只要具有高于室温的熔融温度的材料是聚合物,则用于制备细颗粒乳液; 和(d)冷却用于制备细颗粒悬浮液的细颗粒乳液; 其中所述分散相部分至少在步骤(c)中在85%至99.5%的范围内。
