Abstract
A method for the production of a particulate hydrated gel polymer, which includes heating a hydrated gel polymer possessed of a cross-linked structure to a temperature in the range of from 45.degree. to 90.degree. C. and extruding the resultant hot hydrated gel polymer through a perforated plate containing holes of a diameter in the range of from 6.5 to 18 mm and an absorbent resin which includes drying the resultant particulate hydrated gel polymer.
