摘要： A first crystalline polypropylene of the present invention satisfies the relationships of the following formulae (1) and (2): &agr;≦−0.42×ln(Mp)+7.3  (1),and Tm>1.85×ln(Mp)+144.5  (2), wherein &agr; is a 0° C. soluble content (% by weight) as measured through programmed-temperature fractionation, Mp is a peak molecular weight in a molecular weight distribution curve as measured through gel permeation chromatography, and Tm is a melting point (° C.) as measured through differential scanning calorimetry. A second crystalline polypropylene of the present invention satisfies the relationship given in the following formula (3): &agr;≦1.11[&eegr;]−0.42+1.40  (3) wherein &agr; is the same as above and [&eegr;] an intrinsic viscosity (dl/g) as measured in a tetralin solvent at 135° C. Moldings and films made of the first or second crystalline polypropylene are highly rigid and have good heat resistance and good scratch resistance.
