Abstract
Provided are a polymer composition that can suppress bubbling during membrane formation and peeling of a laminated membrane and an ion-exchange membrane. The polymer composition is a polymer composition including: a fluorine-containing copolymer including a unit (a) derived from a perfluorovinyl compound having a side chain having an ionic group and a unit (b) derived from a fluoroolefin; and a low molecular weight compound (a) having a functional group represented by —COOX (X is H, NH4, or a monovalent metal ion), wherein a content of the low molecular weight compound (a) is 600 ppm or less based on a mass of the polymer composition.
