摘要： A process for the preparation of monodisperse polymer particles which are formed by contacting monomers with aqueous dispersions comprising monodisperse swellable seed polymers/oligomers, and initiating polymerization in the presence of a steric stabilizer. The resulting swollen seed particles are characterized by the particle mode diameter.

摘要： This invention relates to monodisperse cross-linked polymer particles, comprising particles with a substantially smooth outer surface and an average diameter of less than 1 μm, wherein the particles are solid or porous, and wherein the coefficient of variation (CV) % of the particles, when measured by CPS disk centrifugation analysis, is less than 15%. These monodisperse cross-linked polymer particles may comprise magnetic material and are useful in various application. This invention also relates to monodisperse polymer particles for use as seed particles in the Ugelstad process.
摘要翻译： 本发明涉及单分散交联聚合物颗粒，其包含具有基本平滑的外表面和平均直径小于1μm的颗粒，其中颗粒是固体或多孔的，并且其中颗粒的变异系数（CV）％ ，当通过CPS盘离心分析测量时，小于15％。 这些单分散交联聚合物颗粒可以包括磁性材料，并且可用于各种应用。 本发明还涉及在Ugelstad工艺中用作种子颗粒的单分散聚合物颗粒。
