1. A method for operating a high pressure olefin polymerization reactor, the method comprising:
(a) introducing an initiator stream through an initiator nozzle into the reactor, the initiator stream comprising ethylene and an initiator compound;
(b) introducing an olefin stream through an olefin nozzle into the reactor, the olefin stream comprising ethylene and optionally a comonomer; and
(c) polymerizing ethylene and optionally the comonomer in the presence of the initiator stream in the reactor under high pressure polymerization conditions to produce an ethylene polymer;
wherein an amount of ethylene in the initiator stream based on an amount of ethylene in the olefin stream is from 0.01 to 2 wt. %; and
wherein the reactor is an autoclave reactor.
