Abstract
A method for manufacturing a crosslinked polymer or a salt thereof, including a polymerization step of polymerizing a non-crosslinkable monomer composition containing ethylenically unsaturated carboxylic acid monomers and nitrogen-containing ethylenically unsaturated monomers by precipitation polymerization, wherein the concentration of the non-crosslinkable monomer composition in the polymerization step is 16 mass % or more and 30 mass % or less in a polymerization reaction solution in the polymerization step.
