Abstract
Official abstract text for this publication.
Processes for making water-absorbent cross-linked polymers, such as polyacrylic acids/polyacrylates, using supercritical medium; and water-absorbent polymers, e.g. particles thereof, obtained by such processes, where such particles may be porous.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for making water-absorbing cross-linked polymers comprising the steps of: a) obtaining polymerizable monomers; b) obtaining a supercritical reaction medium; c) obtaining a polymerization initiator system; d) obtaining a cross-linking system; e) combining the polymerizable monomers of step a) and the supercritical reaction medium of step b), the cross-linking compound of step d), and (simultaneously or subsequently) the polymerization initia…
