Methods for manufacturing aryl-aryl coupled polymers |
| abstract |
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). |
