Provided is a catalyst used for a living radical polymerization method, which contains a central element consisting of carbon and at least one halogen atom binding to the central element. Further, a hydrocarbon compound can be used as a catalyst precursor. A monomer having a radical-reactive unsaturated bond is subjected to a radical polymerization reaction in the presence of the catalyst, consequently a polymer having narrow molecular weight distribution can be obtained, and thus the cost of the living radical polymerization can be remarkably reduced. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst used, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (no need of any post-treatments for a molded article), and the like.
提供的是用于活性自由基聚合方法的催化剂,其包含由碳组成的中心元素,并且至少有一个卤素原子与中心元素结合。此外,碳氢化合物可以用作催化剂前体。在催化剂存在的情况下,将具有自由基反应不饱和键的单体进行自由基聚合反应,因此可以获得具有窄分子量分布的聚合物,从而可以显着降低活性自由基聚合的成本。由于催化剂毒性低、使用量少、催化剂溶解性高、反应条件温和、成品无色无味(无需对成型物进行任何后处理)等优点,本发明比传统的活性自由基聚合方法在环保和经济方面更加优越。
