Document Type and Number:
Japanese Patent JPH0214361
Kind Code:
B2
Abstract:
A method of producing a cross- linked polymer comprises continuously feeding an aqueous solution of a monomer and a polymerization initiator into a vessel 5 provided with parallel rotary stirrer shafts 6, finely dividing a water-containing gel polymer produced by the shearing force of the stirrer blades during solution polymerization, and continuously discharging the resultant finely divided gel polymer. The monomer preferably comprises an alpha , beta - ethlenically unsaturated monomer, such as acrylic acid, methacrylic acid, an alkali metal salt or an ammonium salt thereof, acrylamide or methacrylamide, and a cross- linking monomer possessing at least two polymeric double bonds.
