Abstract: A process to prepare an ethylene-based polymer, said process comprising polymerizing a mixture comprising ethylene, at a pressure greater than, or equal to, 100 MPa, in the presence of at least one free-radical initiator; and in a reactor system comprising at least one reactor and at least one Hyper-compressor, and wherein at least one oil formulation, optionally comprising one or more lubrication agents, is added to the Hyper-compressor; and wherein at least one of the following steps takes place: A) thermally treating the one or more lubrication agents, in an oxygen-free atmosphere, to achieve a peroxide level ≤10 ppm, based on the weight of the lubrication agent(s), and then adding said agent(s) to the oil formulation, prior to adding the oil formulation to the Hyper-compressor; or B) thermally treating the oil formulation, in an oxygen-free atmosphere, to achieve a peroxide level ≤10 ppm, based on the weight of the oil formulation, prior to adding the oil formulation to the Hyper-compressor; C) a combination of A and B.

Abstract: The present disclosure provides a composition. In an embodiment, the composition includes an olefin-based polymer and from 0.15 wt % to 15 wt % of an odor suppressant. The odor suppressant includes (i) from 0.05 wt % to 2 wt % of a metal oxide having a band gap greater than 5.0 electron volts (eV), and (ii) from 0.1 wt % to 13 wt % of an acid copolymer. The ratio of metal oxide to acid copolymer is from 1:20 to 1:1. Weight percents are based on the total weight of the composition.
