Abstract:
1. A process for producing high pressure polyethylene, comprising: contacting first amounts of ethylene, a polar comonomer, and one or more C3 to C12 unsaturated modifiers in the presence of a first amount of initiator in a reaction system at sufficient reaction conditions, wherein a reaction system effluent comprises the polyethylene resin, a comonomer recycle stream comprising unreacted polar comonomer, and purge gas recycle stream comprising purge gas; removing at least a portion of the purge gas from purge gas recycle stream; removing at least a portion of the unreacted polar comonomer from the comonomer recycle stream; and continuing the reaction in the reaction system by contacting second portions of ethylene, polar comonomer, and one or more C3 to C12 unsaturated modifiers.
