Title:
POWDERY CROSSLINKED ABSORBENT POLYMER ABSORBING AQUEOUS LIQUID AND BLOOD, METHOD FOR PRODUCING THE SAME, AND USE OF THE SAME
Document Type and Number:
Japanese Patent JP2012097276
Kind Code:
A
Abstract:

To provide a superabsorbent polymer having a level of combined properties where in addition to a retention value of at least 25 g/g or more, an SFC value of at least 30×10-7 or preferably of at least 50×10-7 cm3 s/g is present.

The invention relates to crosslinked polymerizates which are capable of absorbing, which are based on partially neutralized, monoethylenically unsaturated monomers that carry acidic groups, which exhibit improved properties, in particular, with regard to their ability to transport a liquid when in a swollen state, and which are subsequently crosslinked on the surface thereof at a temperature of 150°C or higher with a combination consisting of polyol used as a crosslinker compound and of a cation provided in the form of an aqueous solution.
