The present invention relates to a method for selecting ester functional group-containing polymers from a polymer mixture of the ester functional group-containing polymers and other types of polymers, and more particularly, to a method wherein foreign substances that only exhibit color in the ester functional group-containing polymers are removed from the polymer mixture by using an extracting agent for extracting the foreign substances and decolorized, and then the decolorized polymers are selectively separated by using the color difference with the other non-decolorized polymers.
