IMPREGNATED CALCIUM CARBONATE, METHOD FOR PRODUCING SAME, POLYMER COMPOSITION, AND POLYMER PRECURSOR COMPOSITION

摘要

Provided are an impregnated calcium carbonate that is dustless and has excellent dispersibility in a polymer composition; a method for producing the same; and a polymer composition comprising the impregnated calcium carbonate. The impregnated calcium carbonate is obtained by surface treatment of calcium carbonate using at least one selected from fatty acids, resin acids, and derivatives thereof and by subjecting the resulting surface-treated calcium carbonate to impregnation at a normal temperature using a liquid organic compound in an amount between 3 to 22 parts by weight per 100 parts by weight of the surface-treated calcium carbonate.
