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, T m , in ° C., and a heat of fusion, H f , in J/g, as determined by DSC Crystallinity, where the numerical values of T m and H f correspond to the relationship T m ≧(0.2143*H f )+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. |
