Abstract
The invention provides an ethylene-based polymer formed from at least the following: ethylene and a monomeric chain transfer agent (monomeric CTA) selected from Structure 1: wherein L is selected from a saturated hydrocarbon, a substituted saturated hydrocarbon, an unsaturated hydrocarbon, or a substituted unsaturated hydrocarbon; R1 is selected from hydrogen, a saturated hydrocarbon, a substituted saturated hydrocarbon, an unsaturated hydrocarbon, or a substituted unsaturated hydrocarbon; R2 is selected from hydrogen, a saturated hydrocarbon or a substituted saturated hydrocarbon; R3 is selected from hydrogen, a saturated hydrocarbon or a substituted saturated hydrocarbon; and R4 is selected from a saturated hydrocarbon, a substituted saturated hydrocarbon, an unsaturated hydrocarbon, or a substituted unsaturated hydrocarbon.
