HYPERBRANCHED POLYMERS AND METHODS OF MAKING AND USING SAME.

摘要

A composition comprising a polyethylene wherein the composition is enriched in polymer molecules having topological variations by an enrichment factor 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.
