SUPERABSORBENT POLYMERS FOR HIGHLY FILLED AND FIBER-FREE HYGIENE PRODUCTS

摘要

The present invention relates to a particulate absorbent polymer material having: i) a maximum APCi×10 sec value ≧1.6) for at least one number i selected from the group of integers from 2 to 12 (=APCmax); or ii) a value ≧12 for the sum total of all APCi×10 sec values for all numbers i from the group of integers from 2 to 12 (=APCsum); wherein the APCi×10 sec value is: APCi×10 sec=QIi×10 secvalue2×PIi×10 secvalue where the QIi×10 sec value is the swell index and i×10 seconds after adding the 0.9% by weight NaCl solution, and the PIi×10 sec value is the permeability index and i×10 seconds after adding the 0.9% by weight NaCl solution.
