| titleOfInvention | Method for producing polypropylene film for film capacitor |
| abstract | An object of the present invention is to provide a method for producing a polypropylene film for a film capacitor having a high dielectric breakdown voltage and a low thermal shrinkage rate. A method for producing a polypropylene film for a film capacitor according to the present invention (1) A melt flow rate (MFR) measured at 230 ° C. under a 2.16 kg load is 1 to 10 g / 10 min in accordance with ASTM D1238. (2) The pentad isotactic fraction (mmmm fraction) measured using 13 C-NMR is 98% or more, and (3) obtained by complete combustion in air. (4) Step (I) for producing a propylene homopolymer having an ash content of 30 ppm or less and a chlorine content measured by ion chromatography of 10 ppm or less, and then a sheet from the propylene homopolymer. A polypropylene film for a film capacitor comprising a step (II) for producing and then a step (III) for producing a stretched film from the sheet. The propylene homopolymer obtained in step (I) or the sheet obtained in step (II) includes a step of irradiating with an electron beam at an absorbed dose of 0.1 to 500 kGy. .
