Novel propylene polymer blends

The invention relates to propylene polymer blends comprising 70 - 92 wt% of a propylene homopolymer, 5 - 15 wt% of an elastomeric ethylene-propylene copolymer, 3 - 15 wt% of an ethylene polymer and an ±-nucleating agent. The propylene polymer blends have an excellent impact strength/stiffness balanc...

Beschreibung
Zusammenfassung:	The invention relates to propylene polymer blends comprising 70 - 92 wt% of a propylene homopolymer, 5 - 15 wt% of an elastomeric ethylene-propylene copolymer, 3 - 15 wt% of an ethylene polymer and an ±-nucleating agent. The propylene polymer blends have an excellent impact strength/stiffness balance and optical properties. They are especially suitable for thermoforming and extrusion blow moulding.
