Abstract
The present disclosure provides an ethylene-based polymer composition formed by high pressure (greater or equal to 100 MPa) free radical polymerization. The ethylene-based polymer composition includes ethylene monomer and a mixture of hydrocarbon-based molecules, each hydrocarbon-based molecule comprising three or more terminal alkene groups. The ethylene-based polymer has a melt index (MI) from 0.1 to 1.0 g/10 min.
