Abstract

A composition comprising an ethylene-based polymer, which comprises the following properties: a) (Mw(abs)/Mw(conv)−2.00)*(100,000 g/mol/Mw(abs))*CDF?IR #191 (MW≤10,000 g/mol)≥0.030; and b) a melt index (I2) from 0.30 to 2.50 g/10 min.

Claims (12)

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

a) (Mw(abs)/Mw(conv)−2.00)*(100,000 g/mol/Mw(abs))*CDF IR (MW≤10,000 g/mol)≥0.030; and

b) a melt index (I2) from 0.30 to 2.50 g/10 min.

2. The composition of claim 1 , wherein the ethylene-based polymer has a CDF IR (at MW≤10,000 g/mol)≥0.150.

3. The composition of claim 1 , wherein the ethylene-based polymer has a CDF DV (at a MW≥1.2×10 6 g/mol)≥0.020.

4. The composition of claim 1 , wherein the ethylene-based polymer has a CDF LS (at MW≥750,000 g/mol)≥0.400.

5. The composition of claim 1 , wherein the ethylene-based polymer has Mw(conv)/Mn(conv) from 7.00 to 11.00.

6. The composition of claim 1 , wherein the ethylene-based polymer is formed in a reactor configuration comprising at least one tubular reactor.

7. The composition of claim 1 , wherein the composition further comprises another polymer different from the ethylene-based polymer.

8. The composition of claim 1 , wherein the ethylene-based polymer is a low density polyethylene (LDPE).

9. An article comprising at least one component formed from the composition of claim 1 .

10. The article of claim 9 , wherein the article is a film.
