Title:
PROCESS FOR PRODUCING AQUEOUS SOLUTION OF MONOALLYLAMINE POLYMER
Document Type and Number:
WIPO Patent Application WO/2000/052070
Kind Code:
A1
Abstract:
A process for producing an aqueous solution of a high-molecular monoallylamine polymer having a weight-average molecular weight of 20,000 to 180,000, which comprises polymerizing monoallylamine sulfate in an aqueous medium in the presence of a specific radical polymerization initiator and then neutralizing the reaction mixture with an alkali; and the aqueous solution of a high-molecular monoallylamine polymer. By this process, the aqueous polymer solution, which is useful in various applications, can be industrially advantageously produced highly efficiently.
