    摘要： There are provided a propylene-based polymer characterized in that (1) the xylene-extraction insoluble portion (XI) is 99.0 wt % or greater, (2) the isotactic pentad ratio (IP) is 98.0% or greater as measured by .sup.13 C nuclear magnetic resonance spectroscopy, (3) the isotactic average chain length (N) is 500 or greater, and (4) the total amount of each of the fractions obtained by column separation of the xylene insolubles whose average chain length (N.sub.f) is 800 or greater accounts for 10 wt % or more of the entirety, and a method for its production, as well as a propylene-based polymer composition prepared by combining with this propylene-based polymer at least a nucleating agent in the range of 0.05-15 wt %. In addition, there are provided a polymerization catalyst component allowing the production of such a propylene-based polymer, and a method for its production.
