Propylene polymers with reduced tendency to stress whitening
Polypropylene with reduced white fracture contains: (A) 70-95 wt.% of a high grade isotactic polypropylene or propylene copolymer with an alpha -olefin containing at least 50 mol% of propylene, and with isotactic index above 90 and melt flow index 0.1-100 g/10 minutes, and (B) 5 - 30 wt.% of a high...
