A reducing agent is then added to quench the oxidation reaction to obtain a mixed aqueous solution containing a reduced form of the N-oxyl compound and a polyethylene glycol derivative having a carboxyl group at a terminal. Step 2:　The mixed aqueous solution which has been adjusted to a pH of 3.0 or less is mixed with an organic solvent containing one or more selected from the group consisting of aromatic hydrocarbons, carboxylic acid alkyl esters, and halogenated hydrocarbons, at 0°C or higher, and the mixture is separated into an organic layer and a water layer. Step 3:　The organic layer obtained in step 2 and an aqueous solution adjusted to a pH of 3.0 or less are mixed at 0°C or higher, and the mixture is separated into an organic layer and a water layer. Step 4:　A polyethylene glycol derivative having a carboxyl group is recovered by concentrating the organic layer obtained in step 3.
