METHOD FOR TREATING WATER-CONTAINING GEL OF (METH)ACRYLIC ACID (SALT)-BASED WATER SOLUBLE POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method for treating the water-containing gel of a (meth)acrylic acid (salt)-based water soluble polymer, capable of obtaining the (meth)acrylic acid (salt)-based water soluble polymer excellent in water solubility and sufficiently reducing its insoluble portion efficiently.;SOLUTION: This method for treating the water-containing gel of the (meth)acrylic acid (salt)-based water soluble polymer by an extrusion process is provided with that the extrusion process is performed by extruding the water-containing gel by applying 0.04-0.12 kWh/kg specific power.;COPYRIGHT: (C)2006,JPO&NCIPI
