PROBLEM TO BE SOLVED: To provide a method of production for an inexpensive acrylamide based nonionic thickener capable of imparting dispersing property to stock fibers for tissue paper, paper towel or the like mixed with a cationic agent, and capable of effectively and stably paper making. SOLUTION: This method of producing the nonionic thickener for paper making by polymerizing polymerizable monomers containing an acrylamide monomer in an aqueous solution, the monomers in the aqueous solution is polymerized in a condition set pH 3-7 and temperature at -5 to 60 deg.C. |
