Abstract
A polymer composition comprises at least two polymer components, the first component having an ATREF peak temperature, Tpeak1, and a viscosity average molecular weight, Mv1, and the second component having an ATREF peak temperature, Tpeak2, and a viscosity average molecular weight, Mv2, wherein the temperature differential between Tpeak2 and Tpeak1 decreases with increased composition density and Mv1/Mv2 is less than or equal to 1.2. the composition is further characterized as having a Mw/Mn of less than or equal to 3.3, an I10/I2>6.6, and a composition density less than 0.945 gram/cubic centimeter.
