Claim 0:
1. A method for producing an ethylene-based copolymer, comprising a producing mode and a washing mode,
wherein the producing mode includes the steps of:
a) hyper-compressing primarily compressed ethylene, a mixture containing a carboxylic acid-containing comonomer and a polar solvent to produce a compressed material;
b) reacting the compressed material to produce a reaction product including an ethylene-based copolymer; and
c) separating and recovering unreacted residues from the reaction product and introducing the unreacted residue into the mixture of step a), and
wherein the washing mode includes the step of: re-supplying the compressed material produced in step a) to step a) as a mixture, without performing step b).
