1. A composition comprising:
(i) an ethylene-based polymer, wherein the ethylene-based polymer is from 23.19 wt % to 90 wt % based on the total weight of the composition;
(ii) an organic peroxide;
(iii) a triorganophosphine having a Structure (1):

OG Complex Work Unit Chemistry
wherein R1, R2, and R3 each is independently selected from the group consisting of a C1-C40 hydrocarbyl group, a C1-C40 heterohydrocarbyl group, and combinations thereof;
with the proviso that the phosphorus atom is bound to a carbon atom in each of R1, R2, and R3; and
(iv) a protic acid-source compound (“PASC”) selected from the group consisting of a protic acid, a protic acid-generator compound (“PAGC”), and combinations thereof.
