| abstract |
The present invention provides a composition comprising a first composition comprising at least one ethylene-based polymer, wherein the first composition has an MWCDI value greater than 0.9 and a melt satisfying the formula I10/I2 > 7.0 - 1.2 x log (I2). A composition having an index ratio (I10/I2) is provided. The present invention also provides a method of forming a composition comprising at least two ethylene-based polymers comprising the steps of: ethylene in solution in the presence of a catalyst system comprising a metal-ligand complex of structure I described herein, and optionally polymerizing at least one comonomer to form a first ethylenic polymer; and polymerizing ethylene, and optionally at least one comonomer, in the presence of a catalyst system comprising a Ziegler/Natta catalyst to form a second ethylene-based polymer. |
