Zusammenfassung:	The invention relates to a method for improving impact-resistant co-polypropylene stress whitening phenomena. The method includes uniformly mixing (by weight share) 100 co-polypropylene powder with 0.05-0.20 antioxidant 168, 0.025-0.100 antioxidant 1010, and 0.05-0.20 neutralizer calcium stearate, and 0.025-0.100 shielding agent titanium dioxide via a high-speed mixer, and extruding for granulation to obtain impact-resistant co-polypropylene with stress whitening phenomena improved. The method does not influence original mechanical property and appearance of impact-resistant co-polypropylene, and has the advantages of small adding amount and low cost. It is economic and easy to be realized in a petroleum and chemical enterprise PP polymerization production device.
