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, molecular oxygen, 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.

Antifoulant and process

The present disclosure provides an ethylene-based polymer. The ethylene-based polymer is formed from reacting, under polymerization conditions, ethylene monomer and bisallyl maleate ('BAIIM'). The present ethylene-based polymer with ethylene monomer and bisallyl maleate branching agent is interchangeably referred to as “BAIIM-PE.”

Ethylene-based polymer composition with branching

The invention provides a composition comprising a first composition, comprising a first ethylene/alpha-olefin/non-conjugated polyene and a second ethylene ethylene/alpha-olefin/non-conjugated polyene, and wherein the first composition comprises the following property: Mw>1389.6 [g/mole] MV+115,000 g/mole, wherein MV is the Mooney Viscosity (ML 1+4, 125 C), and Mw N is the weight average molecular weight, as determined by conventional GPC.
