An ethylene polymer having a polydispersity index ranging from about 8 to about 25 and a level of long chain branching ranging from about 0.001 LCB/103 carbons to about 1.5 LCB/103 carbons as determined by SEC-MALS.
First claim
Opening claim text (preview).
What is claimed is: 1. An ethylene polymer having a density greater than 0.950 g/ml, a level of short chain branching ranging from 3.1 SCB/10 3 carbons to 3.2 SCB/10 3 carbons, a level of long chain branching ranging from about 0.001 LCB/10 3 carbons to about 1.5 LCB/10 3 carbons as determined by SEC-MALS, and a melt index of greater than about 200 g/10 min at 190° C. and 2.16 kg as determined in accordance with ASTM D1238. 2. The polymer of claim 1 having a weight-average molecular weight ranging from about 25 Kg/mol to about 250 Kg/mol. 3. The polymer of claim 1 having a polydispersity index of from about 4 to about 40. 4. The polymer of claim 1 having at least two types of short chain branching. 5. The polymer of claim 4 wherein the types of short chain branching are selected from the group consisting of methyl, ethyl, butyl, hexyl, 4-methylpentyl and octyl. 6. The polymer of claim 1 having a flow activation energy of from about 35 kJ mol −1 to about 70 kJ mol −1 . 7. An ethylene polymer having a density of greater than 0.950 g/ml; a level of short chain branching ranging from 3:1 SCB/10 3 carbons to 3.2 SCB/10 3 carbons; a length of short chain branching wherein less than about 10% of the short-chain branches are odd; a level of long chain branching ranging from about 0.001 LCB/10 3 carbons to about 1.5 LCB/10 3 carbons as determined by SEC-MALS; a melt index of greater than about 200 g/10 min at 190° C. and 216 kg as determined in accordance with ASTM D1238; and methyl, ethyl, and butyl short chain branching.
