To provide a method for producing industrially efficiently handling with good polyvinylamine solution with a high-performance.
Containing N- vinylcarboxamide monomer unit, after producing the polymer which is the value of weight average molecular weight Mw / number average molecular weight Mn of 5 or more in an aqueous solution static adiabatic thermal polymerization, an alkali said polymer and the hydrolysis is carried out in an aqueous solvent in the presence of anti-gelling agent. In a preferred embodiment of the present invention, (co) after producing the polymer, and dried powdered The volatiles to give a 0.1 to 12 wt% of the polymer powder, and store the powder obtained or polymer transported to the site of use of the solution, in place of use of the polymer required during or polymer solution of the solution, the hydrolysis is carried out in an aqueous medium in the presence of an alkali and anti-gelling agent.
