Title:
METHOD OF DISSOLVING WATER-SOLUBLE POLYMER
Document Type and Number:
WIPO Patent Application WO/2010/050416
Kind Code:
A1
Abstract:
A method of dissolving a water-soluble polymer which comprises diluting 2-30 times a primary aqueous solution (8) containing, dissolved therein, 0.3-1 mass% water-soluble polymer just before use to prepare a secondary aqueous solution and subjecting the secondary aqueous solution to an application as a polymeric coagulant, yield improver for papermaking, thickener, paper strength agent, etc. For diluting the primary aqueous solution to prepare the secondary aqueous solution, it is preferred to use an in-line mixer (4). By using the dissolution method, an aqueous water-soluble-polymer solution can be provided which does not decrease in viscosity and can be used over long.
