摘要：
The invention provides a polymer having a melt index ranging from about 0.01 to about 100 g/10 min, a density ranging from about 0.90 to about 0.97 g/cm 3 , a polydispersity ( M w / M n ) between about 2.5 and about 20, a shear ratio (HLMI/MI) between about 10 and about 250, and a molecular weight distribution comprising a peak centered below a molecular weight of 100,000 and a high molecular weight component that extends to molecular weights above 10,000,000 where the percentage of the mass above 1,000,000 ranges from about 0.2 to about 4% of the mass of said polymer, and a process for producing the polymer.
