Purification Methods and Purified Conjugated Polymers
Metal complexing agents are used to purify polymers including conducting polymers to provide very low metal content. The process comprises precipitating the polymer in solution into a solvent system comprising the metal complexing agent. Very low levels including undetectable levels of metals such as nickel and magnesium can be achieved. High purity polymers are used in electronics and photovoltaic applications.
