Abstract:
1. A method for manufacturing polymers through an aryl-aryl coupling reaction, comprising: preparing a reaction medium comprising an aqueous phase and an organic phase; dispersing a water-soluble catalyst in the aqueous phase, the water-soluble catalyst comprising organic ligands complexed with noble metal atoms, the water-soluble catalyst having a greater solubility in the aqueous phase than in the organic phase, wherein the organic ligands are selected from the group consisting of trialkylphosphines, tricycloalkylphosphines, triarylphosphines, dialkylaryiphosphines, alkyldiarylphosphines, heteroarylphosphines, phosphites, phosphinous esters, phosphols, dibenzophosphols, cyclic oligocyclic, polycyclic compounds containing phosphorus atoms, bipyridines, phenanthrolines, porphyrins, alizarins, and combinations thereof, and where the organic ligands further include at least one functional group selected from the group consisting of sulfonic acid groups, carbonic acid groups, phosphonic acid groups, phosphonium groups, peralkylammonium groups, hydroxy groups, and combinations thereof; forming a polymer having a molecular weight greater than about 1000 g/mol by: separating at least a portion of the water soluble catalyst from the polymer by allowing the aqueous phase to separate from the organic phase; and recovering the polymer from the organic phase.
