摘要：
A process for preparing an acrylamide polymer is herein disclosed which comprises the step of initiating polymerization in the presence of an oxidation-reduction system polymerization initiator comprising two or more kinds of oxidizing agents and a reducing agent. According to this process, the polymerization rate can be remarkably increased without bringing about a decrease in the molecular weight of the polymer, and hence, restriction on manufacturing facilities and apparatuses can be relieved and productivity can be remarkably enhanced, which permits a decrease in manufacturing cost.
