Claim 11:
12. A process comprising:
(1) providing a composition, the composition comprising
(A) an ethylene-based polymer, the ethylene-based polymer consisting of (i) ethylene and (ii) an optional C3-C20 α-olefin comonomer and having an amount of at least one volatile carbonyl-containing species;
(B) from 0.15 wt % to 15 wt %, based on total weight of the composition, of an odor suppressant consisting of
(Bi) from 0.05 wt % to 2 wt %, based on total weight of the composition, of a metal oxide having a band gap greater than 5.0 electron volts (eV); and
(Bii) from 0.1 wt % to 13 wt %, based on total weight of the composition, of an acid copolymer composed of (i) ethylene monomer and (ii) a carboxylic acid comonomer or ester derivative thereof, and
(C) optional antioxidant,
wherein (A), (B), (Bi), (Bii), and (C) amount to 100 wt% of the composition; and
wherein the ratio of metal oxide to acid copolymer is from 1:20 to 1:1; and
(2) neutralizing, with the odor suppressant, at least some of the volatile hetero-carbonyl species to form an odor-reduced composition.
