Abstract
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 I2 relationship: Mw(abs)<A+B(I2), wherein A=2.40×105 g/mole and B=−8.00×103 (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.
