ABSTRACT:
A water-soluble vinyl polymer is produced by polymerizing a water-soluble vinyl monomer in the presence of a catalyst or under the action of ultraviolet rays to prepare a polymer having a degree of polymerization of at least 95%, adjusting the water content of the system containing said polymer to be within the range of from 15 to 30%, and irradiating said system with ionizing radiation.
