摘要： Provided is a process for the polymerization of ethylene comprising introducing ethylene, a liquid light hydrocarbon diluent, at least one catalyst, at least one cocatalyst, and optionally one or more comonomers into a reactor; polymerizing the ethylene and optionally the one or more comonomers in the reactor to produce an ethylene polymer; wherein the reactor is fluidly connected to a cooling system, the cooling system comprising a slurry-free heat exchanger, and the cooling system is configured to receive a vapor stream comprising light hydrocarbon vapor produced in the reactor. Also provided is an ethylene polymer produced from the process for polymerizing ethylene and a system for producing an ethylene polymer.
