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/cm3, a Mw/Mn ratio between about 2.5 and about 20, a shear ratio (HLMI/MI) between about 10 and about 250, and wherein a slope of a log G′ (storage modulus) versus log ω (frequency) curve of the polymer increases over a segment of the frequency range when the frequency is increased from about 0.03 to about 100 rad/s.
A polymer having a melt index ranging from about 0.01 to about 100 g/10 minutes, a density ranging from about 0.90 to about 0.97 g/cm3, a Mw/Mn ratio between about 2.5 and about 20, a shear ratio (HLMI/MI) between about 10 and about 250, and wherein a second derivative of a log G′ (storage modulus) versus log ω (frequency) curve of the polymer has a segment that is positive over a frequency range of about 0.03 to about 100 rad/s.
