Abstract:
A method comprising producing N-vinylformamide, polymerizing a monomer ingredient comprising the N-vinylformamide to produce a polymer comprising N-vinylformamide units, hydrolyzing the polymer using an acid or a base to produce an aqueous solution of a polymer comprising vinylamine units, and using the aqueous solution, wherein the storage period (2) from immediately after the production of the polymer to just before initiation of the production of the aqueous solution of a polymer comprising vinylamine units is made longer than the storage period (3) from immediately after the production of the aqueous solution to just before the use.

Claim (Index 13):
The method according to  claim 3 , wherein a weight average molecular weight of the N-vinylformamide unit-containing polymer is 100,000 or more.
