PROBLEM TO BE SOLVED: To provide a treating method for a (meth)acrylic polymer produced by utilizing the atom transfer radical polymerization. SOLUTION: The treating method, which is for the (meth)acrylic polymer manufactured by utilizing the atom transfer radical polymerization using a transition metal complex as the polymerization catalyst, is characterized by heating the polymer in the presence of an antioxidant at 120-250°C, preferably 140-220°C. The antioxidant is preferably an inhibitor of radical chain reaction, concretely, a phenolic antioxidant and/or an amine antioxidant. Heating the (meth)acrylic polymer in the presence of the antioxidant is preferably conducted in the copresence of a synthetic hydrotalcite, aluminum silicate or magnesium oxide.
