Document Type and Number:
WIPO Patent Application WO/2010/087328
Kind Code:
A1
Abstract:
Provided is a propylene homopolymer suitably usable in a film for condensers having a high voltage resistance. Also provided is an oriented film obtained by orienting said propylene homopolymer. A propylene homopolymer for condensers satisfying the following requirements (i) to (v) and (ix): (i) the MFR being 1-10 g/10 min; (ii)the mesopentad fraction (mmmm) measured by 13C-NMR being 0.940-0.995; (iii) the integrated elution amount measured by CFC at 90°C being less than or equal to 0.5% by weight; (iv) the melting point measured by DSC being higher than or equal to 152°C; (v) the chlorine content being less than or equal to 2 ppm by weight; and (ix) the peak half-width of eluted component amount to elution temperature measured by cross fractionation chromatography (CFC) with the use of o-dichlorobenzene being lower than or equal to 7.0°C and the peak top temperature being 105-130°C.
