    Abstract: The present disclosure provides a process. In an embodiment, the process includes introducing an antifoulant into an ethylene feed of a reactor system. The reactor system includes the ethylene feed, a hyper-compressor, a preheater and a polymerization reactor. The ethylene feed is located upstream of the hyper-compressor. The antifoulant consists of an inhibitor and optionally a solvent. As the ethylene feed is located upstream of the hyper-compressor, the process includes introducing the antifoulant into the ethylene feed upstream of the hyper-compressor. The process further includes adding a free radical initiator to the polymerization reactor. The process further includes polymerizing the ethylene in the polymerization reactor under high pressure free-radical polymerization conditions, and forming an ethylene-based polymer.

    Abstract: A solution polymerization process for producing ethylene-based polymer includes introducing ethylene monomer, hydrocarbon solvent, and Ziegler-Natta catalyst into an entrance of a solution polymerization reactor. An ethylene-based polymer is produced by solution polymerizing the ethylene monomer in hydrocarbon solvent. Subsequently, a catalyst deactivator is introduced into the exit of the solution polymerization reactor, thereby producing hydrochloric acid byproduct. The catalyst deactivator includes long chain carboxylate and at least one cation selected from Groups 1, 2, and 12 of the IUPAC periodic table, with the exception of calcium. The catalyst deactivator reduces the effectiveness of the Ziegler-Natta catalyst and neutralizes the hydrochloric acid by forming a chloride salt other than calcium chloride.
