- ETHYLENE-BASED POLYMERS WITH IMPROVED MELT STRENGTH AND PROCESSES FOR THE SAME

摘要

The present invention provides an ethylene-based polymer formed from at least ethylene and a monomer chain transfer agent (monomer CTA) selected from formula (1). Formula 1 [In the above formula, L is selected from saturated hydrocarbons, substituted saturated hydrocarbons, unsaturated hydrocarbons, or substituted unsaturated hydrocarbons; R ₁ is selected from hydrogen, saturated hydrocarbons, substituted saturated hydrocarbons, unsaturated hydrocarbons, or substituted unsaturated hydrocarbons; R ₂ is selected from hydrogen, a saturated hydrocarbon or a substituted saturated hydrocarbon; R ₃ is selected from hydrogen, saturated or substituted saturated hydrocarbons; R ₄ is selected from saturated hydrocarbons, substituted saturated hydrocarbons, unsaturated hydrocarbons or substituted unsaturated hydrocarbons.
