Abstract
A high-molecular-weight monoallylamine polymer aqueous solution containing a monoallylamine polymer having a weight average molecular weight of 20,000 to 180,000 is prepared by polymerizing a monoallylamine sulfate in an aqueous medium in the presence of a specific radical polymerization initiator, and thereby providing the above high-molecular-weight monoallylamine polymer in an aqueous solution. High-molecular-weight monoallylamine polymer for various uses can be efficiently prepared.
