Abstract
The present disclosure provides a method for analyzing an additive in a water-based polymer sample, comprising the steps of: (S1) putting the water-based polymer sample containing a polymer, the additive, and water as a solvent into a vial; (S2) putting a porous pouch containing a superabsorbent polymer (SAP) into the vial to absorb the water into the superabsorbent polymer; (S3) removing the porous pouch from the vial and collecting the concentrated polymer sample remaining in the vial; and (S4) performing a pyrolysis gas chromatography (Py-GC)/mass spectrometer (MS) analysis by introducing the concentrated polymer sample to the Py-GC/MS.
