Abstract

Cette invention concerne une composition superabsorbante comprenant un superabsorbant (100pbw), de la silice (3-20 pbw), de l'eau (0,5-15pbw) et du glycérol (5-50pbw). La silice est constituée par de la silice poreuse ou bien en contient. La silice enrobe sensiblement les particules superabsorbantes et absorbe l'eau et le glycérol.
