Title:
METHOD FOR PRODUCING VINYL-AMINE-UNIT-CONTAINING POLYMER, AND POLYMERIZATION PRODUCT
Document Type and Number:
WIPO Patent Application WO/2015/156251
Kind Code:
A1
Abstract:
 The present invention pertains to a method for producing a vinyl-amine-unit-containing polymer, the method having a step for preparing a mixture for polymerization (a) that contains N-vinylformamide as a monomer component by using crude N-vinylformamide that contains N-vinylformamide and formamide and has a formamide content of 1 part by mass or more per 100 parts by mass of N-vinylformamide, a step for obtaining a polymerization product (b) that contains an N-vinylformamide-unit-containing polymer and formamide by polymerizing monomer components in the mixture for polymerization (a), and a step for obtaining a hydrolysis product (c) that contains a vinyl-amine-unit-containing polymer by conducting hydrolysis treatment of the polymerization product (b) using an acid or a base.
