Abstract
A composition comprising an ethylene-based polymer is made by a process comprising the steps of: (A) contacting under first polymerization conditions at least ethylene and at least one molecular catalyst to form a first ethylene-based polymer, and (B) contacting under second polymerization conditions the first ethylene-based polymer of (A) with at least additional ethylene and a carbon-carbon free radical initiator of Structure (I): wherein R, R, R, R, Rand Rare each, independently, hydrogen or a hydrocarbyl group and wherein, optionally, two or more R groups (R, R, R, R, Rand R) form a ring structure, with the proviso that at least one of Rand R, and at least one of Rand Ris a hydrocarbyl group of at least two carbon atoms, to form the composition.
