Abstract
The present disclosure provides a composition. In an embodiment, the composition is an ethylene-based polymer composition formed by high pressure (greater or equal to 100 MPa) free radical polymerization. The composition includes ethylene monomer and a mixture of hydrocarbon-based molecules. Each hydrocarbon-based molecule includes three or more internal alkene groups.
