Abstract
A method may include polymerizing ethylene in a tubular reactor, where the polymerization is substantially free of a chain transfer agent. A method may include polymerizing ethylene in a tubular reactor, the ethylene having a specific delivery pressure and the polymerization having one or more specific peak temperatures. The molecular weight of the resulting polyethylene may be controlled by the selection of the delivery pressure and the one or more peak temperatures.
