Abstract
Official abstract text for this publication.
A polymer having a long chain branching content peaking at greater than about 20 long chain branches per million carbon atoms, and a polydispersity index of greater than about 10 wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution. A polymer having a long chain branching content peaking at greater than about 8 long chain branches per million carbon atoms, a polydispersity index of greater than about 20 wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution. A polymer having a long chain branching content peaking at greater than about 1 long chain branches per chain, and a polydispersity index of greater than about 10 wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution.
First claim
Opening claim text (preview).
What is claimed is: 1. A polymer of C 2 -C 8 monoolefin monomers having a polydispersity index of greater than about 20 and a long chain branching content peaking at greater than about 8 long chain branches per million carbon atoms, wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution. 2. The polymer of claim 1 wherein the polymer comprises polyethylene.…
