Method for producing vinylamine unit-containing polymer and polymerization product |
| abstract |
The present invention relates to a method for producing a vinylamine unit-containing polymer, the method comprising: preparing a mixture for polymerization (a) containing N-vinylformamide as a monomer component by using crude N-vinylformamide which contains the N-vinylformamide and formamide and has a content of the formamide of 1 part by mass or more with respect to 100 parts by mass of the N-vinylformamide; obtaining a polymerization product (b) containing an N-vinylformamide unit-containing polymer and formamide by polymerizing the monomer component in the mixture for polymerization (a); and obtaining a hydrolysis product (c) containing a vinylamine unit-containing polymer through a hydrolysis treatment of the polymerization product (b) using an acid or a base. |
