Method for measuring polymer modification ratio
The present invention relates to a method for measuring a polymer modification ratio, and more particularly, to a method for measuring a polymer modification ratio, which includes preparing a first solution by dissolving a polymer mixture containing a modified polymer and an unmodified polymer in a first solvent, injecting the first solution into a column filled with an adsorbent, adsorbing the modified polymer onto the adsorbent, and eluting the first solution in which the unmodified polymer is dissolved, transferring the eluted first solution to a detector, injecting a second solvent into the column to elute the second solution in which the adsorbed modified polymer is dissolved, and transferring the eluted second solution to the detector.
