PCT No. PCT/JP97/01097 Sec. 371 Date Dec. 4, 1997 Sec. 102(e) Date Dec. 4, 1997 PCT Filed Mar. 31, 1997 PCT Pub. No. WO97/38030 PCT Pub. Date Oct. 16, 1997A propylene homopolymer having a high stereo-regularity and an excellent processability during sheet or film formation, characterized in that 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, which are absorption intensities attributed to isoblock chain in xylene-insoluble component by 13C-NMR spectrum:[IB]=[Pmmmr]+[Pmmrr]+[Pmrrm](1)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.
