A propylene homopolymer having a high stereoregularitynand an excellent processability during sheet ornfilm formation, characterized in that it exhibits a melt flownrate (MFR) of from 0.1 to 20 g/10 min., a xylene-solublencomponent content of not more than 6 % by weight and annisoblock content [IB] of at least 3 mol% as determined by thenfollowing equation (1) from Pmmmr, Pmmrr and Pmrrm, which arenabsorption intensities attributed to isoblock chain innxylene-insoluble component by 13 C-NMR spectrum:n [IB] = [Pmmmr] + [Pmmrr] + [Pmrrm] nwherein [Pmmmr], [Pmmrr] and [Pmrrm] are the relativenintensity ratio (mol%) of Pmmmr, Pmmrr and Pmrrm, respectively,nwhich are absorption intensities attributed tonisoblock chain. |
