Kind Code:

A1

Abstract:

　Provided is a method for purifying a triazine-ring-containing polymer, said method comprising: a re-precipitation step in which, after adding a basic organic compound selected from alkylamines and pyridines to a solution containing a triazine-ring-containing polymer, said solution being obtained by reacting a cyanuric halide and a diaminoaryl compound in an organic solvent, said solution is dripped into a poor solvent.
