Hydrolytically Stable Isoelectric Hydrogel Compositions
First Claim
1. A hydrolytically stable isoelectric hydrogel material formed by mixing and/or reacting a mixture comprising an oligo- or polyhydroxy compounds, a single isoelectric compound having a pI value of from 1 to 12, and a difunctional or oligofunctional agent, whereby after said mixed and/or reacting the hydrolytically stable isoelectric hydrogel material formed becomes an ampholytic material.

Abstract
An hydrolytically stable isoelectric hydrogel material comprising a single isoelectric compound having a defined pI value from 1 to 12 being incorporated into a hydrogel formed by reacting an oligo- or polyhydroxy compound with the single iso-electric compound and a difunctional or oligofunctional crosslinker, wherein after incorporation of the single isoelectric compound into the hydrogel, the hydrogel material become'"'"'s an ampholytic material.
