Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an elastomeric polypropylene excellent in transparency. SOLUTION: The elastomeric polypropylene is obtained by using a metallocene catalyst (I) comprising a metallocene compound (A), an activating compound (B) and if desired, an organoaluminum compound (C), a supported metallocene catalyst (II) prepared by supporting the metallocene catalyst (I) on a fine particulate support (D), or a supported metallocene catalyst (III) prepared by adding an organoaluminum compound (E) to the supported metallocene catalyst (II). The polypropylene has (1) an isotactic pentad fraction (mmmm) of 0.150-0.749, (2) a different bond due to a 2, 1-insertion reaction of 0.11-20 mol%, (3) a different bond due to a 1, 3-insertion reaction of 0-10 mol% and (4) a melting point (Tm) of 50-160°C, (1) to (3) being determined from NMR spectra.
