Abstract
An ethylene-based polymer comprising from 0.01 to 25 wt. % of at least one terpene comonomer and a method for producing an ethylene-based polymer under a high-pressure system. The present invention further relates to extrusion coating film applications.
Claims22
An ethylene-based polymer comprising from 0.01 to 25 wt. % of at least one terpene comonomer comprising 1 to 5 isoprene units, based on a total weight of the ethylene-based polymer.
A method to produce an ethylene-based polymer under a high-pressure system comprising:
- feeding an ethylene stream to a polymerization reactor,
- feeding at least one terpene comonomer comprising 1 to 5 isoprene units to the polymerization reactor,
- performing a polymerization reaction in the presence of at least one free radical initiator at a pressure from 1100 to 3500 bar to produce an ethylene-based polymer, and
- recovering the ethylene-based polymer from the polymerization reactor.
