Patent ID: 7875690

Claim:
An ethylene alpha-olefin copolymer, wherein the ethylene alpha-olefin copolymer satisfies the following conditions: a density of 0.927 g/cc or greater, a melt index ratio of (I 21 /I 2 ) of from 15 to 40 dg/min, an ESCR value of 500 hr or greater when measured according to ASTM 1693/B in 10% Igepal, a T 75 -T 25 value of 4 or greater, wherein T 25 is the temperature at which 25% of the eluted polymer is obtained and T 75 is the temperature at which 75% of the eluted polymer is obtained in a TREF experiment, and a F 80 value of 10% or greater, wherein F 80 is the fraction of polymer that elutes below 80° C.
