摘要： Transition metal superoxides of formula M(O2)n, where M is a transition metal and n is equal to the valence of M, may be used as initiators for free radical polymerization, optionally, under conditions of living polymerization, with or without chain transfer agents. Polymers produced have a narrow molecular weight distribution and low polydispersity indexes when chain transfer agents and/or molecular weight controlling agents are used.

摘要： A method has been described of preparing monodisperse polymer particles by free radical polymerization or copolymerization of hydrophobic monomers in a water-based system in the presence of cyclodextrin, characterized in that said free radical polymerization is performed with semi-continuous addition of monomer, wherein said monomer is absent before initiating polymerization, and in that a total solid contents of less than 30% by weight is present in said water-based system, in order to provide monodisperse polymer particles which are very suitable for use in many applications as e.g. in inks or toners, in photonic crystal films, in thermal printing plates for computer-to-plate or computer-to-press applications, in inkjet media, in displays, in photographic films, or as a spacing agent.
摘要翻译：已经描述了一种通过在环糊精存在下通过自由基聚合或水基体系中的疏水性单体的共聚来制备单分散聚合物颗粒的方法，其特征在于所述自由基聚合是通过半连续添加单体进行的，其中所述在开始聚合之前单体不存在，并且在所述水基体系中存在小于30重量％的总固体含量，以提供非常适合用于许多应用的单分散聚合物颗粒，例如在墨水或调色剂中，在光子晶体膜中，在用于计算机到印版或计算机到印刷应用的热敏印刷板中，在喷墨介质，显示器，照相胶片中或作为间隔剂中。
