This invention describes a propylene homopolymer with a high stereoregularity and an excellent processability during sheet or film formation; it exhibits a melt flow rate (MFR) of from 0.1 to 20 g/10 min., a xylene-soluble component content of not more than 6% by weight and an isoblock content [IB] of at least 3 mol% as determined by the following equation (1) from Pmmmr, Pmmrr and Pmrrm, absorption intensities attributed to isoblock chain in xylene-insoluble components analyzed by 13C-NMR spectrum: [IB]=[Pmmmr]+[Pmmrr]+[Pmrrm] (wherein [Pmmmr], [Pmmrr] and [Pmrrm] are the relative intensity ratio (mol%) of Pmmmr, Pmmrr and Pmrrm, respectively, which are absorption intensities attributed to isoblock chain). |
