ABSTRACT:
A method for purifying a polymer comprising providing a first mixture comprising at least one solvent and at least one polymeric material, diluting the first mixture with veratrole to produce a second mixture in which the polymeric material is substantially dissolved at a temperature less than 100° C., performing at least one step selected from (i) contacting the second mixture with an aqueous wash solution, and (ii) filtering the second mixture.
