Patent ID: 7943700

Claim:
A polyethylene (PE) composition comprising: (a) from about 90 to about 95 weight % (based upon the weight of the blend) of a first chromium-catalyzed PE having a density greater than or equal to 0.945 g/cc, a melt index ranging from about 0.05 to about 0.70 g/10 minutes, and a MWD ranging from about 30 to about 40; and (b) from about 5 to about 10 weight % (based upon the weight of the blend) of a second PE, having: (i) a density ranging from about 0.916 to about 0.940 g/cc; (ii) a melt index less than about 0.40 g/10 minutes and a high load melt index from about 0.1 to about 10 g/10 minutes; wherein the melt index of the second PE is less than or equal to the melt index of the first PE; (iii) a MWD ranging from about 1 to about 5, (iv) a CDBI greater than about 50%; and (v) a weight average molecular weight ranging from about 100,000 to about 300,000; wherein the PE composition has an ESCR greater than the ESCR of the first PE.
