ABSTRACT:
A process for producing a substantially nonionic water-soluble acrylamide polymer produced without the occurence of hydrolysis of the acrylamide polymer by heating when the reaction system undergoes an unavoidable heat aging such as due to heat of polymerization comprising polymerizing a comparatively high concentration aqueous solution of acrylamide in the presence of a specific water-soluble nitrogen compound.
