Abstract (en)
[origin: WO02053199A1] The invention relates to non-water soluble hydrogels which can swell in water, and which are coated with steric or electrostatic spacers. Before being coated, the hydrogels comprise the following characteristics: absorbency under load (AUL) (0.7 psi) of at least 20 g/g, and gel strength of at least 1600 Pa. The coated hydrogels preferably have the following characteristics: centrifuge retention capacity (CRC) of at least 24 g/g, saline flow conductivity (SFC) of at least 30 x 10<-7> cm<3> s/g, and free swell rate (FSR) of at least 0.15 g/g s and/or a maximum vortex time of 160 s.
