Abstract
Official abstract text for this publication.
A composition comprising an ethylene-based polymer, the ethylene-based polymer having the following properties: a) at least one incorporated structure derived from a polyene selected from the group consisting of i) through x), as described herein; and b) a Mw(abs) versus I 2 relationship: Mw(abs)<A+B(I2), wherein A=2.40×10 5 g/mole and B=−8.00×10 3 (g/mole)/(dg/min). A composition comprising an ethylene-based polymer, the ethylene-based polymer comprising at least one incorporated structure derived from a polyene selected from the group consisting of i) through x), as described herein, wherein the polymer is formed in a reactor configuration comprising at least one tubular reactor.
First claim
Opening claim text (preview).
We claim: 1. A composition comprising an ethylene-based polymer, the ethylene-based polymer comprising ethylene and at least one asymmetrical polyene as the only monomeric units, comprising the following properties: a) at least one incorporated structure derived from a polyene selected from the group consisting of the following i) through x): wherein n is from 1 to 50;…
