An ethylenic polymer comprising amyl groups from about 0.1 to about 2.0 units per 1000 carbon atoms as determined by Nuclear Magnetic Resonance and both a peak melting temperature, Tm, in °C, and a heat of fusion, Hf, in J/g, as determined by DSC Crystallinity, where the numerical values of Tm and Hf correspond to the relationship Tm > (0.2143*Hf) + 79.643. An ethylenic polymer comprising at least one preparative TREF fraction that elutes at 95 °C or greater using a Preparative Temperature Rising Elution Fractionation method, where at least one preparative TREF fraction that elutes at 95 °C or greater has a gpcBR value greater than 0.05 and less than 5 as determined by gpcBR Branching Index by 3D-GPC, and where at least 5 % of the ethylenic polymer elutes at a temperature of 95 °C or greater based upon the total weight of the ethylenic polymer. |
