Abstract

PURPOSE: To prepare the title polymer having excellent water-solubility even at a high molecular weight, and giving a concentrated sludge which is easily dehydrated, by polymerizing acrylamide monomer in the presence of a specific amount of a water-soluble tertiary alcohol.
CONSTITUTION: Acrylamide monomer or a water-soluble monomer mixture mainly composed of acrylamide, is dissolved in water to a concentration of 15W25 wt.%, and polymerized in the presence of a polymerization initiator and 0.5W15 wt.% (based on the monomer) of a water-soluble tertiary alcohol such as tert-butyl alcohol, 2- methyl-2-butanol, etc. After hydrolyzing the polymer, if necessary, the polymer is crushed, dried at 60W100°C, and further crushed to particles with diameters of 1W2 mm.
