ABSTRACT:
Shell/core distortion-resistant particulates of a partially crosslinked superabsorbent polymer, the gradient of partial crosslinking of which being to such extent that the shells are harder and less flexible than the cores thereof, have a capacity to absorb 0.9% saline water of at least 50 g/g and the modulus of which is at least 35,000 Pa; a bed of a saline water gel of the subject particulates has a saline water absorption of at least 20 g/g and a porosity of at least 500 g.
