A polymer composition is disclosed. The polymer is comprised of a polymer (A) having a sulfo and/or carboxy ammonium zwitterion structure and an organic synthetic polymer (B), wherein either of the following condition (i) or (ii) is satisfied: (i) (A) is a polymer having 0 to 80% by weight of the polyalkylene oxide component, and (ii) (A) is a copolymer having 80% by weight or more of the polyalkylene oxide component and (B) is a polymer comprising polyalkylene oxide as a copolymer component. The polymer composition can be used in the production of fibers, films and other shaped articles. The products utilizing the disclosed polymer composition have excellent hydrophilic properties which are maintained even after exposure to numerous washings.
