Document Type and Number:
Japanese Patent JP3435728
Kind Code:
B2
Abstract:
PURPOSE: To efficiently produce a powdered water-sol. cationic polymer.
CONSTITUTION: A water-sol. cationic polymer is produced by polymerizing an N-vinylcarboxamide alone or its mixture with another copolymerizable water-sol. vinyl compd. in a water-in-oil suspension using a hydrocarbon dispersion medium in the presence of a polyoxyethylene alkyl or alkaryl ether surfactant and an ethylene oxide polymer or an ethylene oxide-propylene oxide copolymer, and hydrolyzing the resulting product with an acid.
