Claims (14)

1. A composition comprising an ethylene-based polymer which comprises the following properties:

a) Molecular Weight Distribution (MWD(conv)) from 3.0 to 7.0 as measured according to conventional Gel Permeation Chromatography (GPC);

b) an infra-red Area Detector Fraction (ADF IR) from 0.230 to 0.260 for molecular weight ≤15,000 g/mol as measured according to GPC using an infra-red detector;

c) a melt index (I 2 ) from 4.0 to 6.5 g/10 min as measured in accordance with ASTM D 1238-10, Condition 190° C./2.16 kg, Procedure B.

2. The composition of claim 1 , wherein the ethylene-based polymer further comprises

d) a light scattering ADF LS from 0.420 to 0.480 for molecular weight ≥500,000 g/mol as measured according to GPC using a light scattering detector.

3. The composition of claim 1 , wherein the ethylene-based polymer further comprises a viscosity ADF DV from 0.200 to 0.260 for molecular weight ≥200,000 g/mol as measured according to GPC using viscosity detector.

4. The composition of claim 1 , wherein the ethylene-based polymer further comprises an absolute weight averaged molecular weight Mw(abs) from 145,000 g/mol to 180,000 g/mol, wherein the absolute weight averaged molecular weight Mw(abs) is measured according to GPC using a light scattering detector.

5. The composition of claim 1 , wherein the ethylene-based polymer has a density from 0.910 to 0.925 g/cc.

6. The composition of claim 1 , wherein ethylene-based polymer comprises an ADF DV ≥0.18, for molecular weight >200,000 g/mole.

7. The composition of claim 1 , wherein ethylene-based polymer has a peak melting temperature (Tm) from 100 to 120° C.

8. The composition of claim 1 , wherein the ethylene-based polymer is a LDPE.
