Beschreibung
Zusammenfassung:	Disclosed herein is a radiation-stable polypropylene resin composition having excellent transparency. It contains a polypropylene resin and per 100 parts by weight of the polypropylene resin, 0.005 - 8 parts by weight of a specific sorbitol derivative, 0.01 - 4 parts by weight of a specific phosphite compound and 0.01 - 4 parts by weight of a specific polyamine compound. Excellent molding flowability can be imparted to this resin composition by subjecting it to thermal degradation at 190.degree.C 270.degree.C in the presence of an organic peroxide until a desired melt index is achieved.
