摘要：
Provided are an impregnated calcium carbonate that hardly flies but has excellent dispersibility in a polymer composition, a method for producing the impregnated calcium carbonate, and a polymer composition including the impregnated calcium carbonate. The impregnated calcium carbonate is obtained by surface treating calcium carbonate with at least one of a fatty acid, a resin acid, and derivatives of them to yield a surface treated calcium carbonate and impregnating the surface treated calcium carbonate with an organic compound in a liquid state at a normal temperature in an amount of 3 to 22 parts by weight with respect to 100 parts by weight of the surface treated calcium carbonate.
