WATER ABSORPTION CAPACITY OF CROSSLINKED, WATER-SWELLABLE POLYMERS

摘要

O.Z. 0050/41007 of the Disclosure: The water absorption capacity of crosslinked, water-swellable polymers is improved by a process in which a water-containing, finely divided polymer gel having a solids content of from 20 to 65% by weight is treated with steam at not less than 50.degree.C, the solids content of the water-containing polymer gel increasing by not more than 30% by weight, and the polymer gel is then dried in a conventional manner.
