A process for preparing an ethylene-based polymer, comprising the step of contacting, under polymerization conditions, ethylene and, optionally, one or more alpha-olefin type comonomers, with at least one free radical initiator of type carbon-carbon hydrocarbyl (CC), chosen from the group consisting of the compounds of structures IV to VIII: 3,4-diethyl-3,4-diphenyl-hexane (structure IV) ** Formula ** 2,7-dimethyl -4,5-diethyl-4,5-diphenyl-octane (DBuDPH) (structure V) ** Formula ** 3,4-dibenzyl-3,4-ditolylhexane (DBnDTH) (structure (VI) ** Formula9 ** 3,4-diethyl-3,4-di (dimethylphenyl) -hexane (structure VII) ** Formula ** and 3,4-dibenzyl-3,4-diphenyl-hexane (structure VIII) ** Formula ** and the Polymerization conditions include a polymerization temperature of 210 ºC to 300 ºC. |
