| titleOfInvention | Crystalline polypropylene and its moldings and films |
| abstract | A first crystalline polypropylene of the present invention satisfies the relationships of the following formulae (1) and (2):wherein alpha 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):wherein alpha is the same as above and [eta] 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. |
