STRETCH BLOW-MOLDED CONTAINERS FROM METALLOCENE PROPYLENE POLYMER COMPOSITIONS |
摘要 |
<p>Stretch blow molded containers produced from a propylene polymer composition produced with a Ziegler Natta catalyst, the propylene polymer composition comprising: A. 25.0 wt % to 65.0 wt % of a homopolymer or minirandom copolymer of propylene containing up to 1.0 wt % of at least one of ethylene and C<SUB>4</SUB>-C<SUB>10</SUB>alpha-olefins, having an isotactic index greater than about 80%; and B. 35.0 wt % to 75.0 wt % of a random copolymer of propylene and at least one olefin chosen from ethylene and C<SUB>4</SUB>-C<SUB>10 </SUB>alpha-olefins, containing about 0.3 to about 30 wt % of said olefin, and having an isotactic index greater than 60.0%; wherein the propylene polymer composition has a melt flow rate of 1 to 25 and a molecular weight distribution greater than 3.5.</p> |
