Abstract
The present disclosure provides a process for producing low density polyethylene with a dissipation factor less than or equal to 1.48×10−4 radian at 2.47 GHz. The process includes free radical high pressure polymerization of ethylene and separation of the unreacted species from the resultant polyethylene to form a recycle stream. The process further includes purging dissipative components from the recycle stream. The purged recycle stream is then introduced into the polymerization reactor.
