    • Aryl-aryl coupled polymers are manufactured using a water-soluble noble metal catalyst. The hydrophilicity of the catalyst facilitates the separation of the catalyst from the polymer product. The method can be generally carried out by preparing a reaction medium comprising an aqueous phase and an organic phase. A water-soluble noble metal catalyst is dispersed in the aqueous phase. A base is also dispersed in the aqueous phase. An aryl-aryl coupled polymer is formed in the reaction medium by (i) adding at least one polymerizable monomer to the reaction mixture; and (ii) mixing the aqueous phase with the organic phase to cause polymerization of the monomer through an aryl-aryl coupling reaction. The polymer has a greater solubility in the organic phase than the aqueous phase. Allowing the organic phase to separate from the aqueous phase separates the water soluble catalyst from the polymer. The reaction can be used to manufacture high molecular weight polymers (e.g., at least 10,000 g/mole) with low quantities of residual metal (e.g., less than 20 ppm).
    • 芳基 - 芳基偶联聚合物是使用水溶性贵金属催化剂制备的。 催化剂的亲水性促进了催化剂与聚合物产物的分离。 该方法通常可以通过制备包含水相和有机相的反应介质进行。 将水溶性贵金属催化剂分散在水相中。 碱也分散在水相中。 通过(i)向反应混合物中加入至少一种可聚合单体,在反应介质中形成芳基 - 芳基偶联聚合物; 和(ii)将水相与有机相混合以使单体通过芳基 - 芳基偶联反应聚合。 聚合物在有机相中的溶解度高于水相。 使有机相与水相分离使水溶性催化剂与聚合物分离。 该反应可用于制备具有少量残余金属(例如小于20ppm)的高分子量聚合物(例如至少10,000g / mol)。
