16 Claims

1. An ethylene-based polymer composition formed by high pressure free radical polymerization comprising:

(i) ethylene monomer and (ii) a mixture of hydrocarbon-based molecules, each hydrocarbon-based molecule comprising three or more terminal alkene groups

to form an ethylene-based copolymer with monomers consisting of (i) and (ii) and having

a melt index (MI) from 0.1 to 1.0 g/10 min, and

an Mw/Mn greater than 20.
