    • A highly active and environment-friendly catalyst for use in a living radical polymerization is provided.A catalyst for use in a living radical polymerization method is provided. The catalyst comprises a central element, which is selected from germanium, tin and antimony, and at least one halogen atom, which is bound to the central element. A monomer having a radical reactive unsaturated bond is subjected to a radical polymerization reaction under the presence of the catalyst, thereby it is possible to obtain a polymer having narrow molecular weight distribution. The present invention has the merits such as low toxicity of the catalyst, a small amount of the catalyst can be used, high solubility of the catalyst, mild reaction conditions, no coloration, no odor (unnecessary post-treatment of molded products). The method of the present invention is more environment-friendly and economical than a conventional living radical polymerization method.
    • 提供了用于活性自由基聚合的高活性和环境友好的催化剂。 提供了一种用于活性自由基聚合方法的催化剂。 该催化剂包括选自锗,锡和锑的中心元素和与中心元素结合的至少一个卤素原子。 具有自由基反应性不饱和键的单体在催化剂的存在下进行自由基聚合反应,从而可以得到分子量分布窄的聚合物。 本发明具有催化剂毒性低,可使用少量催化剂,催化剂溶解性高,反应条件温和,无着色,无异味(成型品不必要后处理)等优点。 本发明的方法比常规的活性自由基聚合方法更环保且更经济。
