Abstract

See full text

Provided are a propylene homopolymer composition for a capacitor film, which can provide a film with excellent high-temperature voltage resistance and excellent thin-film stretchability, a method for producing the same, and a capacitor film. The propylene homopolymer composition for a capacitor film contains 50 to 99% by mass of a propylene homopolymer (A1) having predetermined characteristics and 1 to 50% by mass of a propylene homopolymer (B1) having predetermined characteristics, and has (i) a melt flow rate (MFR) of 1.0 to 10.0 g/10 min and (ii) a chlorine content of 2 ppm by mass or less.
