Abstract: PROBLEM TO BE SOLVED: To provide a method for continuously producing particulate crosslinked gelatinous polymers by copolymerizing water-soluble monoethylenically unsaturated monomers (a) with 0.001 to 5 mol% (based on the monomer (a)) of monomers (b) containing at least two polymerizable groups in a kneader. SOLUTION: The method for producing particulate crosslinked gelatinous polymers is characterized in that at least one of following conditions is satisfied: (1) the degree of charging of the monomers in the kneader is at least 71%; (2) the water-soluble monoethylenically unsaturated monomers contain hydroquinone hemi-ether up to 150 ppm; (3) the polymerization zone temperature is higher than 65°C; and (4) the kneader has back mixing ratio less than 0.33. Further, a material added to an inlet of the kneader is conveyed to an end part of the kneader in the axial direction. COPYRIGHT: (C)2010,JPO&INPIT
