ABSTRACT:
In a process for producing a water-soluble polymer in an easily grindable glassy state by subjecting to aqueous solution polymerization a mixture comprising a monomer composed mainly of a vinyl monomer represented by the general formula (I): ##STR1## and water in an amount of 7 to 18% by weight based on the total weight of the monomer and water, a water-soluble salt in a powdery form is added to and dispersed in the polymerization system and the polymerization is carried out in the state that the powdery salt is dispersed, whereby a water-soluble polymer excellent in flocculating action and dissolving workability is obtained.
