Abstract
Polyethylene compositions including at least 65 wt % ethylene derived units, based upon the total weight of the polyethylene composition, are provided. Films made from these polyethylene compositions are also provided as well as processes for making the same.
Claims25
A polyethylene composition comprising at least 65 wt % ethylene derived units and from 0 to 35 wt % of C3-C12 olefin comonomer derived units, based upon the total weight of the polyethylene composition, wherein the polyethylene composition has:
- a) an RCI,m of 100 kg/mol or greater;
- b) an internal unsaturation as measured by 1H NMR less than 0.30 total internal unsaturations per thousand carbon atoms;
- and
- one or both of:
- c) a Tw1-Tw2 value of from −16 to −38° C.;
- d) an Mw1/Mw2 value of at least 0.9;
- and
- one or more of the following:
- e) a density of from 0.890 g/cm3 to 0.940 g/cm3;
- f) a melt index (MI) of from 0.1 g/10 min to 30 g/10 min;
- g) a melt index ratio (I21/I2) of from 10 to 90;
- h) an Mw/Mn of from 2 to 12;
- i) an Mz/Mw of from 2.2 to 5.0;
- j) an Mz/Mn of from 10 to 40;
- and
- k) a g′(vis) of 0.990 or less.
