Abstract

The present disclosure generally relates to catalyst systems, polyethylene compositions, and uses of such compositions in, e.g., films. In an embodiment is provided a film that includes a polyethylene composition, comprising: ethylene and a C-Colefin comonomer, the polyethylene composition having at least 75 wt % ethylene content and from 0 wt % to 25 wt % of a C-Colefin comonomer content based upon the total weight of the composition as determined by GPC-IR5-LS-VIS, the film having: an average of MD and TD 1% secant modulus of 42,000 psi or greater as determined by ASTM D-882, and a Dart Drop Impact of greater than 400 g/mil, as determined by ASTM D1709. In another embodiment is provided a process for producing a polyethylene composition, comprising: introducing, under first polymerization conditions, ethylene and a C-Calpha-olefin to a catalyst system in a reactor, the catalyst system comprising a first catalyst compound, a second catalyst compound, and an activator; and forming a polyethylene composition.
