Claim 8:
9. An ethylene polymer having:
a melt index of less than or equal to about 0.7 g/10 min;
a density in a range from about 0.94 to about 0.965 g/cm3;
a Mw in a range from about 100,000 to about 200,000 g/mol;
a relaxation time from about 0.5 to about 3 sec;
an average number of long chain branches (LCBs) per 1,000,000 total carbon atoms of the ethylene polymer in a molecular weight range of 1,000,000 to 2,000,000 g/mol of less than or equal to about 4; and
a maximum ratio of extensional viscosity to three times shear viscosity (ηE/3η) at an extensional rate of 0.1 sec−1 in a range from about 1.2 to about 10.
