PROPYLENE HOMOPOLYMER COMPOSITION FOR CAPACITOR FILM, METHOD FOR PRODUCING SAME, AND CAPACITOR FILM

摘要

Provided are: a propylene homopolymer composition for a capacitor film, from which a thin film can be easily produced and which has excellent film high temperature withstand voltage properties; a method for producing same; and a capacitor film. The propylene homopolymer composition for a capacitor film is characterized by containing not less than 1 mass % but less than 50 mass % of (A1) a propylene homopolymer having prescribed characteristics and more than 50 mass % but not more than 99 mass % of (B1) a propylene homopolymer having prescribed characteristics, and characterized in that (i) the melt flow rate (MFR) is 1.0-10.0 g/10 min and (ii) the chlorine content is 2 ppm by mass or less.
