Abstract: Dispersions are prepared by dispersing a polymer precursor such as a polyol into a non-aqueous fluid. The resulting droplets of the polymer precursor is partially polymerized to produce liquid or partially gelled droplets, and then sized to a target particle size. The sized particles are then cured to form solid particles. The process allows for close control of particle size, allows for good control of temperature, and is amenable to batch, semi-continuous or even continuous operation. The resulting dispersions are useful as electrorheological fluids.

Abstract translation: 通过将聚合物前体如多元醇分散在非水溶液中制备分散体。 所得到的聚合物前体的液滴被部分聚合以产生液体或部分胶凝的液滴，然后将其尺寸设定为目标粒度。 然后将大小的颗粒固化以形成固体颗粒。 该方法允许对颗粒尺寸的密切控制，允许良好的温度控制，并且适于分批，半连续或甚至连续操作。 所得分散体可用作电流变流体。
