Abstract
Official abstract text for this publication.
A composition comprising a polyethylene wherein the composition is enriched in polymer molecules having topological variations by an enrichment factor ω and wherein the composition displays a long chain branching frequency of greater than about 0.5 long chain branches per 1000 total carbon atoms. A composition comprising an isolated Ziegler-catalyzed polyethylene having a long chain branching frequency of greater than about 0.5 long chain branches per 1000 total carbon atoms at the high molecular weight end.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising a polyethylene wherein the composition is enriched in polymer molecules having topological variations by an enrichment factor ω, wherein ω is greater than about 2, and wherein the composition displays a long chain branching frequency of greater than about 0.5 long chain branches per 1000 total carbon atoms, wherein the topological variations comprise long chain branching, wherein the enrichment factor ω is determined using a Ziegler-c…
