Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, and polymeric materials formed from the reaction mixtures are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds with a single carbon atom between the two dithiocarbamate or dithiocarbonate groups. Polymeric materials such as homopolymers, random copolymers, and block copolymers can be prepared using the controlled radical initiators.
提供了受控自由基引发剂、含有受控自由基引发剂和各种乙烯不饱和单体的反应混合物,以及由反应混合物形成的聚合物材料。受控自由基引发剂是双二硫代氨基甲酸酯或双二硫代碳酸酯化合物,在两个二硫代氨基甲酸酯或二硫代碳酸酯基团之间有一个碳原子。使用受控自由基引发剂可以制备均聚物、无规共聚物和嵌段共聚物等聚合物材料。
