摘要:
Stretch blow molded containers comprising a propylene polymer composition produced with a metallocene catalyst, the propylene polymer composition comprising: A. 25.0 wt % to about 75.0 wt % of a homopolymer or minirandom copolymer of propylene containing up to 1.0 wt % of at least one of ethylene and C4-C10 α-olefins, having an isotactic index greater that about 80%; and B. 25.0 wt % to about 75.0 wt % of a random copolymer of propylene and at least one olefin chosen from ethylene anti C4-C10 α-olefins, containing about 0.3 to about 30 wt % of said olefin, and having an isotactic index greater than about 60%; wherein the propylene copolymer composition has a melt flow rate of 1 to 50 and a molecular weight distribution or less than 3.5.
